[{"title":"Multi-view causal representation learning with partial observability","abstract":[{"text":"We present a unified framework for studying the identifiability of representations learned from simultaneously observed views, such as different data modalities. We allow a partially observed setting in which each view constitutes a nonlinear mixture of a subset of underlying latent variables, which can be causally related. We prove that the information shared across all subsets of any number of views can be learned up to a smooth bijection using contrastive learning and a single encoder per view. We also provide graphical criteria indicating which latent variables can be identified through a simple set of rules, which we refer to as identifiability algebra. Our general framework and theoretical results unify and extend several previous work on multi-view nonlinear ICA, disentanglement, and causal representation learning. We experimentally validate our claims on numerical, image, and multi-modal data sets. Further, we demonstrate that the performance of prior methods is recovered in different special cases of our setup. Overall, we find that access to multiple partial views offers unique opportunities for identifiable representation learning, enabling the discovery of latent structures from purely observational data.","lang":"eng"}],"publication_status":"published","external_id":{"arxiv":["2311.04056"]},"article_processing_charge":"No","OA_place":"repository","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"full_name":"Yao, Dingling","id":"d3e02e50-48a8-11ee-8f62-c108061797fa","last_name":"Yao","first_name":"Dingling"},{"last_name":"Xu","first_name":"Danru","full_name":"Xu, Danru"},{"last_name":"Lachapelle","first_name":"Sébastien","full_name":"Lachapelle, Sébastien"},{"first_name":"Sara","last_name":"Magliacane","full_name":"Magliacane, Sara"},{"first_name":"Perouz","last_name":"Taslakian","full_name":"Taslakian, Perouz"},{"full_name":"Martius, Georg","first_name":"Georg","last_name":"Martius"},{"first_name":"Julius von","last_name":"Kügelgen","full_name":"Kügelgen, Julius von"},{"last_name":"Locatello","first_name":"Francesco","full_name":"Locatello, Francesco","orcid":"0000-0002-4850-0683","id":"26cfd52f-2483-11ee-8040-88983bcc06d4"}],"ddc":["000"],"conference":{"name":"ICLR: International Conference on Learning Representations","start_date":"2024-05-07","end_date":"2024-05-07","location":"Vienna, Austria"},"has_accepted_license":"1","file":[{"creator":"dernst","success":1,"content_type":"application/pdf","file_name":"2024_ICLR_Yao.pdf","date_created":"2025-02-04T12:34:23Z","file_size":1713606,"date_updated":"2025-02-04T12:34:23Z","checksum":"8ed3c34706eeec622c7e8968dc0f747a","relation":"main_file","access_level":"open_access","file_id":"18995"}],"quality_controlled":"1","corr_author":"1","publication":"12th International Conference on Learning Representations","year":"2024","date_created":"2024-02-07T14:28:34Z","arxiv":1,"department":[{"_id":"FrLo"}],"publisher":"Curran Associates","date_updated":"2025-02-11T10:34:32Z","month":"11","language":[{"iso":"eng"}],"date_published":"2024-11-07T00:00:00Z","oa":1,"file_date_updated":"2025-02-04T12:34:23Z","_id":"14946","type":"conference","acknowledgement":"This work was initiated at the Second Bellairs Workshop on Causality held at the Bellairs Research Institute, January 6–13, 2022; we thank all workshop participants for providing a stimulating research environment.

Knowledge about the structural proteins that form the viral core has remained sparse. While major core proteins have been annotated via indirect experimental evidence, their structures have remained elusive and they could not be assigned to individual core features. Hence, which proteins constitute which layers of the core, such as the palisade layer and the inner core wall, has remained enigmatic. Here we show, using a multi-modal cryo-electron microscopy (cryo-EM) approach in combination with AlphaFold molecular modeling, that trimers formed by the cleavage product of VACV protein A10 are the key component of the palisade layer. This allows us to place previously obtained descriptions of protein interactions within the core wall into perspective and to provide a detailed model of poxvirus core architecture. Importantly, we show that interactions within A10 trimers are likely generalizable over members of orthopox- and parapoxviruses.","lang":"eng"}],"status":"public","day":"01","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"OA_type":"hybrid","citation":{"chicago":"Datler, Julia, Jesse Hansen, Andreas Thader, Alois Schlögl, Lukas W Bauer, Victor-Valentin Hodirnau, and Florian KM Schur. “Multi-Modal Cryo-EM Reveals Trimers of Protein A10 to Form the Palisade Layer in Poxvirus Cores.” <i>Nature Structural &#38; Molecular Biology</i>.

From measurements of magnetization, specific heat, and resistivity, we determine a rich phase diagram as a function of temperature and magnetic field in which different magnetic phases are found. Besides clear evidence of magnetic frustration is obtained from entropy analysis. At zero field, a second-order antiferromagnetic transition occurs at TN1≈1 K followed by a first-order transition at TN2≈0.45 K. With magnetic field new magnetic phases appear, including a weakly first-order transition which ends in a classical critical point and a third magnetic phase.

This approximation assumes that the timescale of the laser-molecule interaction is significantly shorter than the internal rotational period of the molecule, resulting in the rotational motion being instantaneously “frozen” during the interaction. This simplified description of the laser-molecule interaction is incorporated in various theoretical models predicting rotational dynamics of molecules driven by short laser pulses. In this theoretical work, we develop an effective theory for ultrashort laser pulses by examining the full time-evolution operator and solving the time-dependent Schrödinger equation at the operator level. Our findings reveal a critical angular momentum, lcrit, at which the impulsive limit breaks down. In other words, the validity of the sudden approximation depends not only on the pulse duration but also on its intensity, since the latter determines how many angular momentum states are populated. We explore both ultrashort multicycle (Gaussian) pulses and the somewhat less studied half-cycle pulses, which produce distinct effective potentials. We discuss the limitations of the impulsive limit and propose a method that rescales the effective matrix elements, enabling an improved and more accurate description of laser-molecule interactions."}],"external_id":{"arxiv":["2307.07256"],"isi":["001158043800006"]},"publication_status":"published","issue":"2","publication_identifier":{"eissn":["2469-9934"],"issn":["2469-9926"]},"doi":"10.1103/PhysRevA.109.023101","publication":"Physical Review A","year":"2024","date_created":"2024-02-18T23:01:01Z","article_number":"023101","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2307.07256"}],"corr_author":"1","quality_controlled":"1","_id":"15004","scopus_import":"1","article_type":"original","oa_version":"Preprint","intvolume":"       109","acknowledgement":"We thank Bretislav Friedrich, Marjan Mirahmadi, Artem Volosniev, and Burkhard Schmidt for insightful discussions.

They have wide applications ranging from computer science to economics and biology. Yet, even though an agent’s payoff only depends on the actions of their direct neighbors in graphical games, computing the Nash equilibria and making statements about the convergence time of \"natural\" local dynamics in particular can be highly challenging. In this work, we present a novel approach for classifying complexity of Nash equilibria in graphical games by establishing a connection to local graph algorithms, a subfield of distributed computing. In particular, we make the observation that the equilibria of graphical games are equivalent to locally verifiable labelings (LVL) in graphs; vertex labelings which are verifiable with constant-round local algorithms. This connection allows us to derive novel lower bounds on the convergence time to equilibrium of best-response dynamics in graphical games. Since we establish that distributed convergence can sometimes be provably slow, we also introduce and give bounds on an intuitive notion of \"time-constrained\" inefficiency of best responses. We exemplify how our results can be used in the implementation of mechanisms that ensure convergence of best responses to a Nash equilibrium. Our results thus also give insight into the convergence of strategy-proof algorithms for graphical games, which is still not well understood."}],"external_id":{"arxiv":["2102.13457"],"isi":["001585185800011"]},"publication_status":"published","article_processing_charge":"No","volume":286,"author":[{"first_name":"Juho","last_name":"Hirvonen","full_name":"Hirvonen, Juho"},{"full_name":"Schmid, Laura","id":"38B437DE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6978-7329","last_name":"Schmid","first_name":"Laura"},{"last_name":"Chatterjee","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Schmid, Stefan","first_name":"Stefan","last_name":"Schmid"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","project":[{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","call_identifier":"H2020","grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E"}],"citation":{"short":"J.

Existing oblivious routing schemes with polylogarithmic competitive ratio for general networks are tree-based, in the sense that routing is performed according to a convex combination of trees. However, this restriction to trees leads to a construction that has time quadratic in the size of the network and does not parallelize well. \r\nIn this paper we study oblivious routing schemes based on electrical routing. In particular, we show that general networks with n vertices and m edges admit a routing scheme that has competitive ratio O(log² n) and consists of a convex combination of only O(√m) electrical routings. This immediately leads to an improved construction algorithm with time Õ(m^{3/2}) that can also be implemented in parallel with Õ(√m) depth."}],"publication_status":"published","external_id":{"isi":["001300389400055"],"arxiv":["2303.02491"]},"article_processing_charge":"No","volume":287,"author":[{"last_name":"Goranci","first_name":"Gramoz","full_name":"Goranci, Gramoz"},{"last_name":"Henzinger","first_name":"Monika H","full_name":"Henzinger, Monika H","id":"540c9bbd-f2de-11ec-812d-d04a5be85630","orcid":"0000-0002-5008-6530"},{"full_name":"Räcke, Harald","first_name":"Harald","last_name":"Räcke"},{"full_name":"Sachdeva, Sushant","first_name":"Sushant","last_name":"Sachdeva"},{"full_name":"Sricharan, A.

The recent “Sparsity May Cry” (SMC) benchmark put into question the validity of all existing methods, exhibiting a more complex setup where many known pruning methods appear to fail. We revisit the question of accurate BERT-pruning during fine-tuning on downstream datasets, and propose a set of general guidelines for successful pruning, even on the challenging SMC benchmark. First, we perform a cost-vs-benefits analysis of pruning model components, such as the embeddings and the classification head; second, we provide a simple-yet-general way of scaling training, sparsification and learning rate schedules relative to the desired target sparsity; finally, we investigate the importance of proper parametrization for Knowledge Distillation in the context of LLMs. Our simple insights lead to state-of-the-art results, both on classic BERT-pruning benchmarks, as well as on the SMC benchmark, showing that even classic gradual magnitude pruning (GMP) can yield competitive results, with the right approach.","lang":"eng"}],"title":"How to prune your language model: Recovering accuracy on the \"Sparsity May Cry\" benchmark","date_created":"2024-02-18T23:01:03Z","year":"2024","publication_identifier":{"eissn":["2640-3498"]},"publication":"Proceedings of Machine Learning Research","corr_author":"1","quality_controlled":"1","main_file_link":[{"open_access":"1","url":"https://proceedings.mlr.press/v234/kurtic24a"}],"conference":{"end_date":"2024-01-06","location":"Hongkong, China","name":"CPAL: Conference on Parsimony and Learning","start_date":"2024-01-03"}},{"related_material":{"record":[{"status":"public","id":"21253","relation":"later_version"}]},"volume":14465,"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","author":[{"full_name":"Pach, János","id":"E62E3130-B088-11EA-B919-BF823C25FEA4","last_name":"Pach","first_name":"János"},{"id":"f86f7148-b140-11ec-9577-95435b8df824","full_name":"Saghafian, Morteza","last_name":"Saghafian","first_name":"Morteza"},{"last_name":"Schnider","first_name":"Patrick","full_name":"Schnider, Patrick"}],"title":"Decomposition of geometric graphs into star-forests","abstract":[{"lang":"eng","text":"We solve a problem of Dujmović and Wood (2007) by showing that a complete convex geometric graph on n vertices cannot be decomposed into fewer than n-1 star-forests, each consisting of noncrossing edges.

The assessment of the layer and the interface qualities for a buried strained Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping confirmed that the reduction of the growth temperature enables the 2-dimensional growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless, dislocations at the top and/or bottom interface of the Ge layer were observed by means of electron channeling contrast imaging, suggesting the importance of the careful dislocation assessment. The interface abruptness does not depend on the selection of the precursor gases, but it is strongly influenced by the growth temperature which affects the coverage of the surface H-passivation. The mobility of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010 /cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the heterostructure thanks to the high Si0.3Ge0.7 SRB quality.","lang":"eng"}],"author":[{"full_name":"Shimura, Yosuke","last_name":"Shimura","first_name":"Yosuke"},{"full_name":"Godfrin, Clement","last_name":"Godfrin","first_name":"Clement"},{"first_name":"Andriy","last_name":"Hikavyy","full_name":"Hikavyy, Andriy"},{"full_name":"Li, Roy","first_name":"Roy","last_name":"Li"},{"first_name":"Juan L","last_name":"Aguilera Servin","orcid":"0000-0002-2862-8372","id":"2A67C376-F248-11E8-B48F-1D18A9856A87","full_name":"Aguilera Servin, Juan L"},{"first_name":"Georgios","last_name":"Katsaros","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8342-202X","full_name":"Katsaros, Georgios"},{"last_name":"Favia","first_name":"Paola","full_name":"Favia, Paola"},{"full_name":"Han, Han","first_name":"Han","last_name":"Han"},{"full_name":"Wan, Danny","last_name":"Wan","first_name":"Danny"},{"full_name":"de Greve, Kristiaan","last_name":"de Greve","first_name":"Kristiaan"},{"first_name":"Roger","last_name":"Loo","full_name":"Loo, Roger"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":174,"OA_place":"publisher","has_accepted_license":"1","ddc":["530"],"file":[{"file_id":"17312","date_updated":"2024-07-22T11:56:08Z","file_size":4220165,"relation":"main_file","checksum":"62e8e9ae960387a3dca32ec7f5e413ab","access_level":"open_access","file_name":"2024_MaterialsScience_Shimura.pdf","content_type":"application/pdf","date_created":"2024-07-22T11:56:08Z","creator":"dernst","success":1}],"quality_controlled":"1","doi":"10.1016/j.mssp.2024.108231","publication_identifier":{"issn":["1369-8001"]},"issue":"5","publication":"Materials Science in Semiconductor Processing","date_created":"2024-02-22T14:10:40Z","year":"2024","article_number":"108231","date_published":"2024-05-20T00:00:00Z","month":"05","language":[{"iso":"eng"}],"date_updated":"2025-04-14T08:01:27Z","department":[{"_id":"GeKa"},{"_id":"NanoFab"}],"publisher":"Elsevier","isi":1,"file_date_updated":"2024-07-22T11:56:08Z","oa":1,"scopus_import":"1","_id":"15018","intvolume":"       174","oa_version":"Published Version","article_type":"original","acknowledgement":"The Ge project received funding from the European Union's Horizon Europe programme under the Grant Agreement 101069515 – IGNITE.

We formalize such beliefs as maximum-entropy Bayesian priors, constrained by the expected utility. We explore how such priors aid inference of system parameters with limited data and enable optimality hypothesis testing: is the utility higher than by chance?\r\nChapter 3 examines the ultimate biological optimization process: evolution by natural selection. As some individuals survive and reproduce more successfully than others, populations evolve towards fitter genotypes and phenotypes. We formalize this as accumulation of genetic information, and use population genetics theory to study how much such information can be accumulated per generation and maintained in the face of random mutation and genetic drift. We identify the population size and fitness variance as the key quantities that control information accumulation and maintenance.\r\nChapter 4 reuses the concept of genetic information from Chapter 3, but from a different perspective: we ask how much genetic information organisms actually need, in particular in the context of gene regulation. For example, how much information is needed to bind transcription factors at correct locations within the genome? Population genetics provides us with a refined answer: with an increasing population size, populations achieve higher fitness by maintaining more genetic information. Moreover, regulatory parameters experience selection pressure to optimize the fitness-information trade-off, i.e. minimize the information needed for a given fitness. This provides an evolutionary derivation of the optimization priors introduced in Chapter 2.\r\nChapter 5 proves an upper bound on mutual information between a signal and a communication channel output (such as neural activity). Mutual information is an important utility measure for biological systems, but its practical use can be difficult due to the large dimensionality of many biological channels. Sometimes, a lower bound on mutual information is computed by replacing the high-dimensional channel outputs with decodes (signal estimates). Our result provides a corresponding upper bound, provided that the decodes are the maximum posterior estimates of the signal.","lang":"eng"}],"article_processing_charge":"No","page":"158","related_material":{"record":[{"id":"7606","relation":"part_of_dissertation","status":"public"},{"status":"public","relation":"part_of_dissertation","id":"12081"},{"relation":"part_of_dissertation","id":"7553","status":"public"}]},"acknowledged_ssus":[{"_id":"ScienComp"}],"OA_place":"publisher","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","author":[{"full_name":"Hledik, Michal","id":"4171253A-F248-11E8-B48F-1D18A9856A87","last_name":"Hledik","first_name":"Michal"}],"ddc":["576","519"],"has_accepted_license":"1","file":[{"date_updated":"2024-02-23T13:50:53Z","file_size":7102089,"relation":"main_file","checksum":"b2d3da47c98d481577a4baf68944fe41","access_level":"open_access","file_id":"15021","creator":"mhledik","success":1,"content_type":"application/pdf","file_name":"hledik thesis pdfa 2b.pdf","date_created":"2024-02-23T13:50:53Z"},{"file_id":"15022","access_level":"closed","relation":"source_file","checksum":"eda9b9430da2610fee7ce1c1419a479a","file_size":14014790,"date_updated":"2024-02-23T14:20:16Z","date_created":"2024-02-23T13:50:54Z","file_name":"hledik thesis source.zip","content_type":"application/zip","creator":"mhledik"}],"corr_author":"1","publication_identifier":{"issn":["2663-337X"]},"doi":"10.15479/at:ista:15020","date_created":"2024-02-23T14:02:04Z","year":"2024","date_updated":"2026-04-07T12:59:25Z","department":[{"_id":"GradSch"},{"_id":"NiBa"},{"_id":"GaTk"}],"publisher":"Institute of Science and Technology Austria","date_published":"2024-02-23T00:00:00Z","language":[{"iso":"eng"}],"month":"02","file_date_updated":"2024-02-23T14:20:16Z","oa":1,"_id":"15020","type":"dissertation","oa_version":"Published Version","project":[{"call_identifier":"H2020","name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385"},{"grant_number":"RGP0034/2018","_id":"2665AAFE-B435-11E9-9278-68D0E5697425","name":"Can evolution minimize spurious signaling crosstalk to reach optimal performance?"},{"name":"Understanding the evolution of continuous genomes","_id":"bd6958e0-d553-11ed-ba76-86eba6a76c00","grant_number":"101055327"}],"citation":{"short":"M.

The effects of these correlations on the solvent itself remain, however, much less clear. In particular, the addition of salt has been consistently reported to affect the solution’s viscosity, but most modeling attempts fail to reproduce experimental data even at moderate salt concentrations. Here, we use an approach based on stochastic density functional theory, which accurately captures charge fluctuations and correlations. We derive a simple analytical expression for the viscosity correction in concentrated electrolytes, by directly linking it to the liquid’s structure factor. Our prediction compares quantitatively to experimental data at all temperatures and all salt concentrations up to the saturation limit. This universal link between the microscopic structure and viscosity allows us to shed light on the nanoscale dynamics of water and ions under highly concentrated and correlated conditions.","lang":"eng"}],"article_processing_charge":"Yes (in subscription journal)","title":"Correlation-induced viscous dissipation in concentrated electrolytes","volume":160,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","author":[{"id":"48c58128-57b0-11ee-9095-dc28fd97fc1d","orcid":"0000-0002-5728-9189","full_name":"Robin, Paul","first_name":"Paul","last_name":"Robin"}],"pmid":1},{"_id":"15025","scopus_import":"1","article_type":"original","oa_version":"Preprint","intvolume":"        34","type":"journal_article","acknowledgement":"The first author was supported by the ERC Advanced Grant “RMTBeyond” No. 101020331.

The current models place GN at the Golgi apparatus (GA), where it mediates secretion/recycling, and at the plasma membrane (PM) presumably contributing to clathrin-mediated endocytosis (CME). The mechanistic basis of the developmental function of GN, distinct from the other ARF-GEFs including its closest homologue GNOM-LIKE1 (GNL1), remains elusive. Insights from this study largely extend the current notions of GN function. We show that GN, but not GNL1, localizes to the cell periphery at long-lived structures distinct from clathrin-coated pits, while CME and secretion proceed normally in <jats:italic>gn</jats:italic> knockouts. The functional GN mutant variant GN<jats:sup>fewerroots</jats:sup>, absent from the GA, suggests that the cell periphery is the major site of GN action responsible for its developmental function. Following inhibition by Brefeldin A, GN, but not GNL1, relocates to the PM likely on exocytic vesicles, suggesting selective molecular associations en route to the cell periphery. A study of GN-GNL1 chimeric ARF-GEFs indicates that all GN domains contribute to the specific GN function in a partially redundant manner. Together, this study offers significant steps toward the elucidation of the mechanism underlying unique cellular and development functions of GNOM.","lang":"eng"}],"publication_status":"published","external_id":{"isi":["001174278000001"],"pmid":["38381485"]},"article_processing_charge":"Yes"},{"volume":65,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","author":[{"first_name":"Atul","last_name":"Varshney","full_name":"Varshney, Atul","orcid":"0000-0002-3072-5999","id":"2A2006B2-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Ghazaryan, Areg","orcid":"0000-0001-9666-3543","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan","first_name":"Areg"},{"first_name":"Artem","last_name":"Volosniev","full_name":"Volosniev, Artem","orcid":"0000-0003-0393-5525","id":"37D278BC-F248-11E8-B48F-1D18A9856A87"}],"title":"Classical ‘spin’ filtering with two degrees of freedom and dissipation","keyword":["Atomic and Molecular Physics","and Optics"],"abstract":[{"lang":"eng","text":"Coupling of orbital motion to a spin degree of freedom gives rise to various transport phenomena in quantum systems that are beyond the standard paradigms of classical physics.

The simulations demonstrate that the mesoscale organization of convection, a process that cannot be physically represented by conventional global climate models, is important for the variations of tropical daily accumulated precipitation extremes. In both the simulations and observations, daily precipitation extremes increase in a more organized state, in association with larger, but less frequent, storms. Repeating the simulations for a warmer climate results in a robust increase in monthly-mean daily precipitation extremes. Higher precipitation percentiles have a greater sensitivity to convective organization, which is predicted to increase with warming. Without changes in organization, the strongest daily precipitation extremes over the tropical oceans increase at a rate close to Clausius-Clapeyron (CC) scaling. Thus, in a future warmer state with increased organization, the strongest daily precipitation extremes over oceans increase at a faster rate than CC scaling."}],"external_id":{"isi":["001300045100007"],"pmid":["38394192"]},"publication_status":"published","article_processing_charge":"Yes","related_material":{"link":[{"url":"https://ista.ac.at/en/news/cloud-clustering-causes-more-extreme-rain/","relation":"press_release","description":"News on ISTA Website"}]},"pmid":1,"volume":10,"OA_place":"publisher","author":[{"full_name":"Bao, Jiawei","id":"bb9a7399-fefd-11ed-be3c-ae648fd1d160","first_name":"Jiawei","last_name":"Bao"},{"first_name":"Bjorn","last_name":"Stevens","full_name":"Stevens, Bjorn"},{"full_name":"Kluft, Lukas","last_name":"Kluft","first_name":"Lukas"},{"id":"f978ccb0-3f7f-11eb-b193-b0e2bd13182b","orcid":"0000-0001-5836-5350","full_name":"Muller, Caroline J","last_name":"Muller","first_name":"Caroline J"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345"},{"citation":{"apa":"Jin, S., Dai, K., Verstraten, J., Dixmerias, M., Al Hyder, R., Salomon, C., … Yefsah, T.

They are, however, often optimized to address a specific type of problem. Here, we present the design and implementation of a 6Li-based quantum gas platform that provides wide-ranging capabilities and is able to address a variety of quantum many-body problems. Our two-chamber architecture relies on a robust combination of gray molasses and optical transport from a laser-cooling chamber to a glass cell with excellent optical access. There, we first create unitary Fermi superfluids in a three-dimensional axially symmetric harmonic trap and characterize them using in situ thermometry, reaching temperatures below 20 nK. This allows us to enter the deep superfluid regime with samples of extreme diluteness, where the interparticle spacing is sufficiently large for direct single-atom imaging. Second, we generate optical lattice potentials with triangular and honeycomb geometry in which we study diffraction of molecular Bose-Einstein condensates, and show how going beyond the Kapitza-Dirac regime allows us to unambiguously distinguish between the two geometries. With the ability to probe quantum many-body physics in both discrete and continuous space, and its suitability for bulk and single-atom imaging, our setup represents an important step towards achieving a wide-scope quantum simulator.","lang":"eng"}],"keyword":["General Physics and Astronomy"],"title":"Multipurpose platform for analog quantum simulation","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"full_name":"Jin, Shuwei","last_name":"Jin","first_name":"Shuwei"},{"last_name":"Dai","first_name":"Kunlun","full_name":"Dai, Kunlun"},{"full_name":"Verstraten, Joris","first_name":"Joris","last_name":"Verstraten"},{"full_name":"Dixmerias, Maxime","last_name":"Dixmerias","first_name":"Maxime"},{"first_name":"Ragheed","last_name":"Al Hyder","full_name":"Al Hyder, Ragheed","id":"d1c405be-ae15-11ed-8510-ccf53278162e"},{"full_name":"Salomon, Christophe","first_name":"Christophe","last_name":"Salomon"},{"first_name":"Bruno","last_name":"Peaudecerf","full_name":"Peaudecerf, Bruno"},{"first_name":"Tim","last_name":"de Jongh","full_name":"de Jongh, Tim"},{"first_name":"Tarik","last_name":"Yefsah","full_name":"Yefsah, Tarik"}],"volume":6}]
