Building upon a symmetric Galerkin boundary element method, we first compute stress intensity factors following the theory of linear elastic fracture mechanics. We then use these stress intensities to simulate the motion of a propagating crack front at a significantly higher resolution than the overall deformation of the breaking object. Allowing for spatial variations of the material's toughness during crack propagation produces visually realistic, highly-detailed fracture surfaces. Furthermore, we introduce approximations for stress intensities and crack opening displacements, resulting in both practical speed-up and theoretically superior runtime complexity compared to previous methods. While we choose a quasi-static approach to fracture mechanics, ignoring dynamic deformations, we also couple our fracture simulation framework to a standard rigid-body dynamics solver, enabling visual effects artists to simulate both large scale motion, as well as fracturing due to collision forces in a combined system. As fractures inside of an object grow, their geometry must be represented both in the coarse boundary element mesh, as well as at the desired fine output resolution. Using a boundary element method, we avoid complicated volumetric meshing operations. Instead we describe a simple set of surface meshing operations that allow us to progressively add cracks to the mesh of an object and still re-use all previously computed entries of the linear boundary element system matrix. On the high resolution level, we opt for an implicit surface representation. We then describe how to capture fracture surfaces during crack propagation, as well as separate the individual fragments resulting from the fracture process, based on this implicit representation. We show results obtained with our method, either solving the full boundary element system in every time step, or alternatively using our fast approximations. These results demonstrate that both of these methods perform well in basic test cases and produce realistic fracture surfaces. Furthermore we show that our fast approximations substantially out-perform the standard approach in more demanding scenarios. Finally, these two methods naturally combine, using the full solution while the problem size is manageably small and switching to the fast approximations later on. The resulting hybrid method gives the user a direct way to choose between speed and accuracy of the simulation.

Here we focus on such heavy-hole states confined in germanium hut wires. By tuning the growth density of the latter we can realize a T-like structure between two neighboring wires. Such a structure allows the realization of a charge sensor, which is electrostatically and tunnel coupled to a quantum dot, with charge-transfer signals as high as 0.3 e. By integrating the T-like structure into a radiofrequency reflectometry setup, single-shot measurements allowing the extraction of hole tunneling times are performed. The extracted tunneling times of less than 10 μs are attributed to the small effective mass of Ge heavy-hole states and pave the way toward projective spin readout measurements."}],"citation":{"ieee":"L.

In particular, near-rotary-resonance relaxation dispersion (NERRD) experiments probe angular backbone motion, while Bloch–McConnell relaxation dispersion data report on fluctuations of the local electronic environment. These experiments and simulations reveal that the packing of the protein can significantly alter the thermodynamics and kinetics of local conformational exchange. Moreover, we report small-amplitude reorientational motion of protein molecules in the crystal lattice with an ~3–5° amplitude on a tens-of-microseconds time scale in one of the crystals, but not in others. An intriguing possibility arises that overall motion is to some extent coupled to local dynamics. Our study highlights the importance of considering the packing when analyzing dynamics of crystalline proteins.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s41467-017-00165-8"}],"publication":"Nature Communications","date_published":"2017-07-27T00:00:00Z","OA_place":"publisher","publication_identifier":{"issn":["2041-1723"]},"publisher":"Springer Nature","title":"Slow conformational exchange and overall rocking motion in ubiquitin protein crystals","type":"journal_article","oa_version":"Published Version","article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","status":"public","publication_status":"published","date_updated":"2025-01-22T14:32:38Z","intvolume":"         8","doi":"10.1038/s41467-017-00165-8","scopus_import":"1","article_processing_charge":"Yes","language":[{"iso":"eng"}],"OA_type":"gold","_id":"8445"},{"citation":{"apa":"Akopyan, A., &#38; Vysotsky, V.

When selection fluctuates in time, it is unclear whether frequency-independent selection may maintain genetic polymorphism without invoking additional mechanisms. We show that constant frequency-independent selection with arbitrary epistasis on a well-mixed haploid population eliminates genetic variation if we assume linkage equilibrium between alleles. To this end, we introduce the notion of frequency-independent selection at the level of alleles, which is sufficient to prove our claim and contains the notion of frequency-independent selection on haploids. When selection and recombination are weak but of the same order, there may be strong linkage disequilibrium; numerical calculations show that stable equilibria are highly unlikely. Using the example of a diallelic two-locus model, we then demonstrate that frequency-independent selection that fluctuates in time can maintain stable polymorphism if linkage disequilibrium changes its sign periodically. We put our findings in the context of results from the existing literature and point out those scenarios in which the possible role of frequency-independent selection in maintaining genetic variation remains unclear.\r\n","lang":"eng"}],"citation":{"ama":"Novak S, Barton NH.

These fundamentally differ in character from the radiatively-driven dry pools defining convective aggregation. Advancement in remote sensing and in computer capabilities has promoted exploration of how precipitation-induced cold pool processes modify the convective spectrum and life cycle. This contribution surveys current understanding of such cold pools over the tropical and subtropical oceans. In shallow convection with low rain rates, the cold pools moisten, preserving the near-surface equivalent potential temperature or increasing it if the surface moisture fluxes cannot ventilate beyond the new surface layer; both conditions indicate downdraft origin air from within the boundary layer. When rain rates exceed ∼ 2 mm h−1, convective-scale downdrafts can bring down drier air of lower equivalent potential temperature from above the boundary layer. The resulting density currents facilitate the lifting of locally thermodynamically favorable air and can impose an arc-shaped mesoscale cloud organization. This organization allows clouds capable of reaching 4–5 km within otherwise dry environments. These are more commonly observed in the northern hemisphere trade wind regime, where the flow to the intertropical convergence zone is unimpeded by the equator. Their near-surface air properties share much with those shown from cold pools sampled in the equatorial Indian Ocean. Cold pools are most effective at influencing the mesoscale organization when the atmosphere is moist in the lower free troposphere and dry above, suggesting an optimal range of water vapor paths. Outstanding questions on the relationship between cold pools, their accompanying moisture distribution and cloud cover are detailed further. Near-surface water vapor rings are documented in one model inside but near the cold pool edge; these are not consistent with observations, but do improve with smaller horizontal grid spacings."}],"citation":{"mla":"Zuidema, Paquita, et al. “A Survey of Precipitation-Induced Atmospheric Cold Pools over Oceans and Their Interactions with the Larger-Scale Environment.” <i>Surveys in Geophysics</i>, vol. 38, no. 6, Springer Nature, 2017, pp. 1283–305, doi:<a href=\"https://doi.org/10.1007/s10712-017-9447-x\">10.1007/s10712-017-9447-x</a>.","ama":"Zuidema P, Torri G, Muller CJ, Chandra A.

While there is a rich history of observational work on convective clustering and organization, there have been only a few studies that have analyzed observations to look specifically for processes related to self-aggregation in models. Here we review observational work in both of these categories and motivate the need for more of this work. We acknowledge that self-aggregation may appear to be far-removed from observed convective organization in terms of time scales, initial conditions, initiation processes, and mean state extremes, but we argue that these differences vary greatly across the diverse range of model simulations in the literature and that these comparisons are already offering important insights into real tropical phenomena. Some preliminary new findings are presented, including results showing that a self-aggregation simulation with square geometry has too broad distribution of humidity and is too dry in the driest regions when compared with radiosonde records from Nauru, while an elongated channel simulation has realistic representations of atmospheric humidity and its variability. We discuss recent work increasing our understanding of how organized convection and climate change may interact, and how model discrepancies related to this question are prompting interest in observational comparisons. We also propose possible future directions for observational work related to convective aggregation, including novel satellite approaches and a ground-based observational network.","lang":"eng"}],"extern":"1","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","page":"1199-1236","type":"journal_article","oa_version":"Published Version","keyword":["Geochemistry and Petrology","Geophysics"],"article_type":"original","title":"Observing convective aggregation","article_processing_charge":"No","language":[{"iso":"eng"}],"_id":"9138","intvolume":"        38","doi":"10.1007/s10712-017-9419-1","status":"public","issue":"6","publication_status":"published","date_updated":"2022-01-24T12:43:13Z"},{"citation":{"ieee":"J.

The terminal investment hypothesis predicts that individuals faced with a reduced survival should invest more into reproduction instead of maintenance and growth. Several studies suggest that individuals are indeed able to estimate their body condition and to increase their reproductive effort with approaching death, while other studies gave ambiguous results. We investigate whether queens of a perennial social insect (ant) are able to boost their reproduction following infection with an obligate killing pathogen. Social insect queens are special with regard to reproduction and aging, as they outlive conspecific non-reproductive workers. Moreover, in the ant Cardiocondyla obscurior, fecundity increases with queen age. However, it remained unclear whether this reflects negative reproductive senescence or terminal investment in response to approaching death. Here, we test whether queens of C. obscurior react to infection with the entomopathogenic fungus Metarhizium brunneum by an increased egg-laying rate. We show that a fungal infection triggers a reinforced investment in reproduction in queens. This adjustment of the reproductive rate by ant queens is consistent with predictions of the terminal investment hypothesis and is reported for the first time in a social insect."}],"publication":"Royal Society Open Science","external_id":{"isi":["000406670000025"]},"date_published":"2017-07-05T00:00:00Z","file_date_updated":"2020-07-14T12:48:15Z","acknowledgement":"We thank two anonymous reviewers for helpful suggestions on the manuscript.","publication_identifier":{"issn":["2054-5703"]},"publist_id":"6527","has_accepted_license":"1","publisher":"Royal Society, The","isi":1,"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"volume":4,"date_created":"2018-12-11T11:49:10Z","article_number":"170547","day":"05","year":"2017","oa":1,"month":"07","quality_controlled":"1","author":[{"full_name":"Giehr, Julia","last_name":"Giehr","first_name":"Julia"},{"full_name":"Grasse, Anna V","id":"406F989C-F248-11E8-B48F-1D18A9856A87","first_name":"Anna V","last_name":"Grasse"},{"last_name":"Cremer","first_name":"Sylvia","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2193-3868","full_name":"Cremer, Sylvia"},{"first_name":"Jürgen","last_name":"Heinze","full_name":"Heinze, Jürgen"},{"full_name":"Schrempf, Alexandra","last_name":"Schrempf","first_name":"Alexandra"}],"related_material":{"record":[{"relation":"research_data","id":"9853","status":"public"}]},"status":"public","publication_status":"published","issue":"7","date_updated":"2025-07-10T12:01:39Z","intvolume":"         4","doi":"10.1098/rsos.170547","scopus_import":"1","article_processing_charge":"No","language":[{"iso":"eng"}],"ddc":["576","592"],"_id":"914","file":[{"date_created":"2018-12-12T10:08:24Z","content_type":"application/pdf","date_updated":"2020-07-14T12:48:15Z","access_level":"open_access","checksum":"351ae5e7a37e6e7d9295cd41146c4190","file_name":"IST-2017-849-v1+1_2017_Grasse_Cremer_AntQueens.pdf","relation":"main_file","file_size":530412,"file_id":"4684","creator":"system"}],"title":"Ant queens increase their reproductive efforts after pathogen infection","pubrep_id":"849","department":[{"_id":"SyCr"}],"type":"journal_article","oa_version":"Published Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"page":"4990-4999","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","ec_funded":1,"project":[{"call_identifier":"FP7","grant_number":"616160","name":"Discrete Optimization in Computer Vision: Theory and Practice","_id":"25FBA906-B435-11E9-9278-68D0E5697425"}],"type":"conference","oa_version":"Submitted Version","department":[{"_id":"VlKo"}],"title":"A message passing algorithm for the minimum cost multicut problem","ddc":["000"],"file":[{"content_type":"application/pdf","date_created":"2019-01-18T12:52:46Z","access_level":"open_access","date_updated":"2020-07-14T12:48:15Z","file_name":"Swoboda_A_Message_Passing_CVPR_2017_paper.pdf","checksum":"7e51dacefa693574581a32da3eff63dc","file_size":883264,"relation":"main_file","file_id":"5849","creator":"dernst"}],"_id":"915","article_processing_charge":"No","language":[{"iso":"eng"}],"scopus_import":"1","doi":"10.1109/CVPR.2017.530","intvolume":"      2017","conference":{"location":"Honolulu, HA, United States","start_date":"2017-07-21","end_date":"2017-07-26","name":"CVPR: Computer Vision and Pattern Recognition"},"date_updated":"2024-11-04T13:52:34Z","status":"public","publication_status":"published","quality_controlled":"1","author":[{"first_name":"Paul","last_name":"Swoboda","id":"446560C6-F248-11E8-B48F-1D18A9856A87","full_name":"Swoboda, Paul"},{"full_name":"Andres, Bjoern","last_name":"Andres","first_name":"Bjoern"}],"month":"07","oa":1,"day":"01","year":"2017","date_created":"2018-12-11T11:49:11Z","volume":2017,"isi":1,"publisher":"IEEE","has_accepted_license":"1","publist_id":"6526","date_published":"2017-07-01T00:00:00Z","file_date_updated":"2020-07-14T12:48:15Z","external_id":{"isi":["000418371405009"]},"publication_identifier":{"isbn":["978-153860457-1"]},"abstract":[{"lang":"eng","text":"We propose a dual decomposition and linear program relaxation of the NP-hard minimum cost multicut problem.

But observations only indicate a modest enhancement at this latitude. To resolve this difference between observational and numerical results, the authors study the latitudinal dependence of internal tides’ dissipation in more realistic conditions. In particular, the ocean is not a quiescent medium; the presence of large-scale currents or mesoscale eddies can impact the propagation and dissipation of internal tides. This paper investigates the impact of a weak background mean current in numerical simulations. The authors focus on the local dissipation of high spatial mode internal waves near their generation site. The vertical profile of dissipation and its variation with latitude without the mean current are consistent with earlier studies. But adding a weak mean current has a major impact on the latitudinal distribution of dissipation. The peak at the critical latitude disappears, and the dissipation is closer to a constant, albeit with two weak peaks at ~25° and ~35° latitude. This disappearance results from the Doppler shift of the internal tides’ frequency, which hinders the nonlinear transfer of energy to small-scale secondary waves via the parametric subharmonic instability (PSI). The new two weak peaks correspond to the Doppler-shifted critical latitudes of the left- and right-propagating waves. The results are confirmed in simulations with simple sinusoidal topography. Thus, although nonlinear transfers via PSI are efficient at dissipating internal tides, the exact location of the dissipation is sensitive to large-scale oceanic conditions.","lang":"eng"}],"publisher":"American Meteorological Society","publication_identifier":{"issn":["0022-3670","1520-0485"]},"date_published":"2017-06-01T00:00:00Z","date_created":"2021-02-15T15:11:04Z","year":"2017","day":"01","volume":47,"month":"06","author":[{"full_name":"Richet, O.","last_name":"Richet","first_name":"O."},{"full_name":"Muller, Caroline J","first_name":"Caroline J","last_name":"Muller","orcid":"0000-0001-5836-5350","id":"f978ccb0-3f7f-11eb-b193-b0e2bd13182b"},{"full_name":"Chomaz, J.-M.","last_name":"Chomaz","first_name":"J.-M."}],"quality_controlled":"1","oa":1},{"year":"2017","day":"01","date_created":"2018-12-11T11:49:11Z","volume":2017,"author":[{"last_name":"Swoboda","first_name":"Paul","id":"446560C6-F248-11E8-B48F-1D18A9856A87","full_name":"Swoboda, Paul"},{"full_name":"Rother, Carsten","last_name":"Rother","first_name":"Carsten"},{"first_name":"Carsten","last_name":"Abu Alhaija","full_name":"Abu Alhaija, Carsten"},{"full_name":"Kainmueller, Dagmar","last_name":"Kainmueller","first_name":"Dagmar"},{"first_name":"Bogdan","last_name":"Savchynskyy","full_name":"Savchynskyy, Bogdan"}],"quality_controlled":"1","month":"01","oa":1,"corr_author":"1","abstract":[{"text":"We study the quadratic assignment problem, in computer vision also known as graph matching.

After stem cell division, daughter cells that exit the stem cell domain acquire transit amplifying cell identity before they are incorporated into organs and differentiate. In this study, we used an integrated approach to elucidate the role of HECATE (HEC) genes in regulating developmental trajectories of shoot stem cells in Arabidopsis thaliana. Our work reveals that HEC function stabilizes cell fate in distinct zones of the shoot meristem thereby controlling the spatio-temporal dynamics of stem cell differentiation. Importantly, this activity is concomitant with the local modulation of cellular responses to cytokinin and auxin, two key phytohormones regulating cell behaviour. Mechanistically, we show that HEC factors transcriptionally control and physically interact with MONOPTEROS (MP), a key regulator of auxin signalling, and modulate the autocatalytic stabilization of auxin signalling output.</jats:p>","lang":"eng"}],"citation":{"ama":"Gaillochet C, Stiehl T, Wenzl C, et al.

The new design simplifies the optical assembly and decouples it from the microwave part of the setup. Experimental demonstrations show that the modular device assembly allows us to flexibly tune the microwave coupling to the converter chip while maintaining small loss.

Chapter 1 concerns the plant hormone auxin and its polar transport through cells and tissues. The highly controlled, directional transport of auxin is facilitated by plasma membrane-localized transporters. Transporters from the PIN family direct auxin transport due to their polarized localizations at cell membranes. Substantial effort has been put into research on cellular trafficking of PIN proteins, which is thought to underlie their polar distribution. I participated in a forward genetic screen aimed at identifying novel regulators of PIN polarity. The screen yielded several genes which may be involved in PIN polarity regulation or participate in polar auxin transport by other means. Chapter 2 focuses on the endomembrane system, with particular attention to clathrin-mediated endocytosis. The project started with identification of several proteins that interact with clathrin light chains. Among them, I focused on two putative homologues of auxilin, which in non-plant systems is an endocytotic factor known for uncoating clathrin-coated vesicles in the final step of endocytosis. The body of my work consisted of an in-depth characterization of transgenic A. thaliana lines overexpressing these putative auxilins in an inducible manner. Overexpression of these proteins leads to an inhibition of endocytosis, as documented by imaging of cargoes and clathrin-related endocytic machinery. An extension of this work is an investigation into a concept of homeostatic regulation acting between distinct transport processes in the endomembrane system. With auxilin overexpressing lines, where endocytosis is blocked specifically, I made observations on the mutual relationship between two opposite trafficking processes of secretion and endocytosis. In Chapter 3, I analyze cortical microtubule arrays and their relationship to auxin signaling and polarized growth in elongating cells. In plants, microtubules are organized into arrays just below the plasma membrane, and it is thought that their function is to guide membrane-docked cellulose synthase complexes. These, in turn, influence cell wall structure and cell shape by directed deposition of cellulose fibres. In elongating cells, cortical microtubule arrays are able to reorient in relation to long cell axis, and these reorientations have been linked to cell growth and to signaling of growth-regulating factors such as auxin or light. In this chapter, I am addressing the causal relationship between microtubule array reorientation, growth, and auxin signaling. I arrive at a model where array reorientation is not guided by auxin directly, but instead is only controlled by growth, which, in turn, is regulated by auxin."}],"corr_author":"1","file_date_updated":"2020-07-14T12:48:15Z","date_published":"2017-06-02T00:00:00Z","OA_place":"publisher","publication_identifier":{"issn":["2663-337X"]},"publist_id":"6483","has_accepted_license":"1","publisher":"Institute of Science and Technology Austria","alternative_title":["ISTA Thesis"],"date_created":"2018-12-11T11:49:18Z","day":"02","year":"2017","oa":1,"month":"06","author":[{"full_name":"Adamowski, Maciek","id":"45F536D2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6463-5257","first_name":"Maciek","last_name":"Adamowski"}],"related_material":{"record":[{"status":"public","id":"1591","relation":"part_of_dissertation"}]},"status":"public","publication_status":"published","date_updated":"2026-04-08T14:20:45Z","doi":"10.15479/AT:ISTA:th_842","degree_awarded":"PhD","language":[{"iso":"eng"}],"article_processing_charge":"No","ddc":["581","583","580"],"_id":"938","file":[{"creator":"dernst","file_id":"6215","relation":"source_file","file_size":46903863,"file_name":"2017_Adamowski-Thesis_Source.docx","checksum":"193425764d9aaaed3ac57062a867b315","access_level":"closed","date_updated":"2020-07-14T12:48:15Z","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","date_created":"2019-04-05T09:03:20Z"},{"checksum":"df5ab01be81f821e1b958596a1ec8d21","file_name":"2017_Adamowski-Thesis.pdf","date_updated":"2020-07-14T12:48:15Z","access_level":"open_access","date_created":"2019-04-05T09:03:19Z","content_type":"application/pdf","file_id":"6216","creator":"dernst","file_size":8698888,"relation":"main_file"}],"title":"Investigations into cell polarity and trafficking in the plant model Arabidopsis thaliana ","pubrep_id":"842","department":[{"_id":"JiFr"}],"supervisor":[{"full_name":"Friml, Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596","first_name":"Jiří","last_name":"Friml"}],"type":"dissertation","oa_version":"Published Version","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","page":"117"},{"publication_status":"published","issue":"3","status":"public","date_updated":"2025-06-04T08:20:23Z","intvolume":"       119","doi":"10.1103/PhysRevLett.119.033905","scopus_import":"1","language":[{"iso":"eng"}],"article_processing_charge":"No","_id":"939","title":"Waveguides with absorbing boundaries: Nonlinearity controlled by an exceptional point and solitons","department":[{"_id":"MiLe"}],"oa_version":"Submitted Version","type":"journal_article","project":[{"call_identifier":"FP7","grant_number":"291734","name":"International IST Postdoc Fellowship Programme","_id":"25681D80-B435-11E9-9278-68D0E5697425"}],"ec_funded":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","arxiv":1,"citation":{"apa":"Midya, B., &#38; Konotop, V.

Stable propagation of TE and TM-polarized solitons is accompanied by attenuation of all other modes, i.e., the waveguide features properties of conservative and dissipative systems. If the linear spectrum of the waveguide possesses exceptional points, which occurs in the case of TM polarization, an originally focusing (defocusing) material nonlinearity may become effectively defocusing (focusing). This occurs due to the geometric phase of the carried eigenmode when the surface impedance encircles the exceptional point. In its turn, the change of the effective nonlinearity ensures the existence of dark (bright) solitons in spite of focusing (defocusing) Kerr nonlinearity of the core. The existence of an exceptional point can also result in anomalous enhancement of the effective nonlinearity. In terms of practical applications, the nonlinearity of the reported waveguide can be manipulated by controlling the properties of the absorbing cladding."}],"publication":"Physical Review Letters","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1706.04085 "}],"publication_identifier":{"issn":["0031-9007"]},"date_published":"2017-07-18T00:00:00Z","external_id":{"isi":["000405718200012"],"arxiv":["1706.04085 "]},"publist_id":"6481","publisher":"American Physical Society","isi":1,"volume":119,"date_created":"2018-12-11T11:49:18Z","year":"2017","day":"18","article_number":"033905","oa":1,"month":"07","author":[{"full_name":"Midya, Bikashkali","id":"456187FC-F248-11E8-B48F-1D18A9856A87","first_name":"Bikashkali","last_name":"Midya"},{"full_name":"Konotop, Vladimir","last_name":"Konotop","first_name":"Vladimir"}],"quality_controlled":"1"},{"status":"public","issue":"14","publication_status":"published","date_updated":"2021-01-12T08:22:04Z","intvolume":"       119","doi":"10.1103/PhysRevLett.119.147703","language":[{"iso":"eng"}],"_id":"94","title":"Breaking Lorentz reciprocity with frequency conversion and delay","type":"journal_article","oa_version":"Submitted Version","arxiv":1,"extern":"1","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Rosenthal, Eric, Benjamin Chapman, Andrew P Higginbotham, Joseph Kerckhoff, and Konrad Lehnert. “Breaking Lorentz Reciprocity with Frequency Conversion and Delay.” <i>APS Physics, Physical Review Letters</i>.

The method requires no magnetic materials or resonant physics, allowing for the design of scalable and broadband nonreciprocal circuits. With this approach, two types of gyrators - universal building blocks for linear, nonreciprocal circuits - are constructed. Using one of these gyrators, we create a circulator with &gt;15 dB of isolation across the 5-9 GHz band. Our designs may be readily extended to any platform with suitable frequency conversion elements, including semiconducting devices for telecommunication or an on-chip superconducting implementation for quantum information processing.","lang":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1705.09548","open_access":"1"}],"publication":"APS Physics, Physical Review Letters","date_published":"2017-10-06T00:00:00Z","external_id":{"arxiv":["1705.09548"]},"publist_id":"7960","publisher":"American Physical Society","volume":119,"date_created":"2018-12-11T11:44:35Z","article_number":"147703","day":"06","year":"2017","oa":1,"month":"10","quality_controlled":"1","author":[{"full_name":"Rosenthal, Eric","first_name":"Eric","last_name":"Rosenthal"},{"first_name":"Benjamin","last_name":"Chapman","full_name":"Chapman, Benjamin"},{"first_name":"Andrew P","last_name":"Higginbotham","orcid":"0000-0003-2607-2363","id":"4AD6785A-F248-11E8-B48F-1D18A9856A87","full_name":"Higginbotham, Andrew P"},{"first_name":"Joseph","last_name":"Kerckhoff","full_name":"Kerckhoff, Joseph"},{"first_name":"Konrad","last_name":"Lehnert","full_name":"Lehnert, Konrad"}]}]
