However, most proposed solutions evolve towards a target geometry without considering time-dependent actuation paths. To achieve more complex geometries and avoid self-collisions, it is critical to encode a spatial and temporal shape evolution within the initially flat shell. Recent realizations of time-dependent morphing are limited to the actuation of few, discrete hinges and cannot form doubly curved surfaces. Here, we demonstrate a method for encoding temporal shape evolution in architected shells that assume complex shapes and doubly curved geometries. The shells are non-periodic tessellations of pre-stressed contractile unit cells that soften in water at rates prescribed locally by mesostructure geometry. The ensuing midplane contraction is coupled to the formation of encoded curvatures. We propose an inverse design tool based on a data-driven model for unit cells’ temporal responses.","lang":"eng"}],"pmid":1,"citation":{"short":"R. Guseinov, C. McMahan, J. Perez Rodriguez, C.

We shall be concerned with some mathematical aspects of this complicated problem in many-body quantum mechanics. More specifically, we consider the dilute limit where the scattering length of the interaction potential, which is a measure for the effective range of the potential, is small compared to the average distance between the particles. We are interested in a setting with positive (i.e., non-zero) temperature. After giving a survey of the relevant literature in the field, we provide some facts and examples to set expectations for the two-dimensional system. The crucial difference to the three-dimensional system is that there is no Bose–Einstein condensate at positive temperature due to the Hohenberg–Mermin–Wagner theorem. However, it turns out that an asymptotic formula for the free energy holds similarly to the three-dimensional case.\r\nWe motivate this formula by considering a toy model with δ interaction potential. By restricting this model Hamiltonian to certain trial states with a quasi-condensate we obtain an upper bound for the free energy that still has the quasi-condensate fraction as a free parameter. When minimizing over the quasi-condensate fraction, we obtain the Berezinskii–Kosterlitz–Thouless critical temperature for superfluidity, which plays an important role in our rigorous contribution. The mathematically rigorous result that we prove concerns the specific free energy in the dilute limit. We give upper and lower bounds on the free energy in terms of the free energy of the non-interacting system and a correction term coming from the interaction. Both bounds match and thus we obtain the leading term of an asymptotic approximation in the dilute limit, provided the thermal wavelength of the particles is of the same order (or larger) than the average distance between the particles. The remarkable feature of this result is its generality: the correction term depends on the interaction potential only through its scattering length and it holds for all nonnegative interaction potentials with finite scattering length that are measurable. In particular, this allows to model an interaction of hard disks."}],"citation":{"short":"S.

This so-called Z-ring acts as a scaffold recruiting several division-related proteins to mid-cell and plays a key role in distributing proteins at the division site, a feature driven by the treadmilling motion of FtsZ filaments around the septum. What regulates the architecture, dynamics and stability of the Z-ring is still poorly understood, but FtsZ-associated proteins (Zaps) are known to play an important role. \r\nAdvances in fluorescence microscopy and in vitro reconstitution experiments have helped to shed light into some of the dynamic properties of these complex systems, but methods that allow to collect and analyze large quantitative data sets of the underlying polymer dynamics are still missing.\r\nHere, using an in vitro reconstitution approach, we studied how different Zaps affect FtsZ filament dynamics and organization into large-scale patterns, giving special emphasis to the role of the well-conserved protein ZapA. For this purpose, we use high-resolution fluorescence microscopy combined with novel image analysis workfows to study pattern organization and polymerization dynamics of active filaments. We quantified the influence of Zaps on FtsZ on three diferent spatial scales: the large-scale organization of the membrane-bound filament network, the underlying\r\npolymerization dynamics and the behavior of single molecules.\r\nWe found that ZapA cooperatively increases the spatial order of the filament network, binds only transiently to FtsZ filaments and has no effect on filament length and treadmilling velocity. Our data provides a model for how FtsZ-associated proteins can increase the precision and stability of the bacterial cell division machinery in a\r\nswitch-like manner, without compromising filament dynamics. Furthermore, we believe that our automated quantitative methods can be used to analyze a large variety of dynamic cytoskeletal systems, using standard time-lapse\r\nmovies of homogeneously labeled proteins obtained from experiments in vitro or even inside the living cell.\r\n"}],"citation":{"short":"P.R.

Inspired by the possibility to experimentally manipulate and enhance chemical reactivity in helium nanodroplets, we investigate the rotation of coupled cold molecules in the presence of a many-body environment.\r\nIn this thesis, we introduce new variational approaches to quantum impurities and apply them to the Fröhlich polaron - a quasiparticle formed out of an electron (or other point-like impurity) in a polar medium, and to the angulon - a quasiparticle formed out of a rotating molecule in a bosonic bath.\r\nWith this theoretical toolbox, we reveal the self-localization transition for the angulon quasiparticle. We show that, unlike for polarons, self-localization of angulons occurs at finite impurity-bath coupling already at the mean-field level. The transition is accompanied by the spherical-symmetry breaking of the angulon ground state and a discontinuity in the first derivative of the ground-state energy. Moreover, the type of symmetry breaking is dictated by the symmetry of the microscopic impurity-bath interaction, which leads to a number of distinct self-localized states. \r\nFor the system containing multiple impurities, by analogy with the bipolaron, we introduce the biangulon quasiparticle describing two rotating molecules that align with respect to each other due to the effective attractive interaction mediated by the excitations of the bath.

Despite their remarkable performance in the standard supervised learning scenario, i.e. when models are trained with labeled data and tested on samples that follow a similar distribution, neural networks have been shown to struggle with more advanced generalization abilities, such as transferring knowledge across visually different domains, or generalizing to new unseen combinations of known concepts. In this thesis we argue that, in contrast to the usual black-box behavior of neural networks, leveraging more structured internal representations is a promising direction\r\nfor tackling such problems. In particular, we focus on two forms of structure. First, we tackle modularity: We show that (i) compositional architectures are a natural tool for modeling reasoning tasks, in that they efficiently capture their combinatorial nature, which is key for generalizing beyond the compositions seen during training. We investigate how to to learn such models, both formally and experimentally, for the task of abstract visual reasoning. Then, we show that (ii) in some settings, modularity allows us to efficiently break down complex tasks into smaller, easier, modules, thereby improving computational efficiency; We study this behavior in the context of generative models for colorization, as well as for small objects detection. Secondly, we investigate the inherently layered structure of representations learned by neural networks, and analyze its role in the context of transfer learning and domain adaptation across visually\r\ndissimilar domains.

However, the orthogonal setting of transferring knowledge from a pretrained network to a visually different yet semantically close source is rarely considered: This commonly happens with real-life data, which is not necessarily as clean as the training source (noise, geometric transformations, different modalities, etc.).To tackle such scenarios, we introduce a new, generalized form of fine-tuning, called flex-tuning, in which any individual unit (e.g. layer) of a network can be tuned, and the most promising one is chosen automatically. In order to make the method appealing for practical use, we propose two lightweight and faster selection procedures that prove to be good approximations in practice. We study these selection criteria empirically across a variety of domain shifts and data scarcity scenarios, and show that fine-tuning individual units, despite its simplicity, yields very good results as an adaptation technique. As it turns out, in contrast to common practice, rather than the last fully-connected unit it is best to tune an intermediate or early one in many domain- shift scenarios, which is accurately detected by flex-tuning.","lang":"eng"}],"type":"conference","department":[{"_id":"ChLa"}],"main_file_link":[{"url":"http://arxiv.org/abs/2008.11995","open_access":"1"}],"publisher":"IEEE","date_created":"2020-06-07T22:00:53Z","publication_status":"published","external_id":{"isi":["000578444802027"],"arxiv":["2008.11995"]},"conference":{"name":"WACV: Winter Conference on Applications of Computer Vision","location":"Snowmass Village, CO, United States","start_date":"2020-03-01","end_date":"2020-03-05"},"_id":"7937","scopus_import":"1","month":"03","date_published":"2020-03-01T00:00:00Z","oa":1,"doi":"10.1109/WACV45572.2020.9093635","day":"01","year":"2020","publication_identifier":{"isbn":["9781728165530"]},"article_number":"2180-2189","isi":1,"arxiv":1,"publication":"2020 IEEE Winter Conference on Applications of Computer Vision","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","oa_version":"Preprint","date_updated":"2026-04-08T07:26:44Z","related_material":{"record":[{"relation":"dissertation_contains","id":"8331","status":"deleted"},{"status":"public","relation":"dissertation_contains","id":"8390"}]},"author":[{"first_name":"Amélie","id":"3811D890-F248-11E8-B48F-1D18A9856A87","last_name":"Royer","full_name":"Royer, Amélie","orcid":"0000-0002-8407-0705"},{"id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","full_name":"Lampert, Christoph","last_name":"Lampert","orcid":"0000-0001-8622-7887","first_name":"Christoph"}],"title":"A flexible selection scheme for minimum-effort transfer learning","article_processing_charge":"No","status":"public","language":[{"iso":"eng"}]},{"title":"Localizing grouped instances for efficient detection in low-resource scenarios","author":[{"first_name":"Amélie","orcid":"0000-0002-8407-0705","id":"3811D890-F248-11E8-B48F-1D18A9856A87","full_name":"Royer, Amélie","last_name":"Royer"},{"last_name":"Lampert","full_name":"Lampert, Christoph","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8622-7887","first_name":"Christoph"}],"date_updated":"2026-04-08T07:26:43Z","related_material":{"record":[{"status":"deleted","relation":"dissertation_contains","id":"8331"},{"status":"public","relation":"dissertation_contains","id":"8390"}]},"language":[{"iso":"eng"}],"status":"public","article_processing_charge":"No","oa_version":"Preprint","publication":"IEEE Winter Conference on Applications of Computer Vision","arxiv":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1109/WACV45572.2020.9093288","day":"01","oa":1,"date_published":"2020-03-01T00:00:00Z","article_number":"1716-1725","publication_identifier":{"isbn":["9781728165530"]},"year":"2020","_id":"7936","month":"03","scopus_import":1,"publication_status":"published","date_created":"2020-06-07T22:00:53Z","conference":{"location":" Snowmass Village, CO, United States","name":"WACV: Winter Conference on Applications of Computer Vision","start_date":"2020-03-01","end_date":"2020-03-05"},"external_id":{"arxiv":["2004.12623"]},"department":[{"_id":"ChLa"}],"publisher":"IEEE","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2004.12623"}],"abstract":[{"lang":"eng","text":"State-of-the-art detection systems are generally evaluated on their ability to exhaustively retrieve objects densely distributed in the image, across a wide variety of appearances and semantic categories. Orthogonal to this, many real-life object detection applications, for example in remote sensing, instead require dealing with large images that contain only a few small objects of a single class, scattered heterogeneously across the space. In addition, they are often subject to strict computational constraints, such as limited battery capacity and computing power.To tackle these more practical scenarios, we propose a novel flexible detection scheme that efficiently adapts to variable object sizes and densities: We rely on a sequence of detection stages, each of which has the ability to predict groups of objects as well as individuals. Similar to a detection cascade, this multi-stage architecture spares computational effort by discarding large irrelevant regions of the image early during the detection process. The ability to group objects provides further computational and memory savings, as it allows working with lower image resolutions in early stages, where groups are more easily detected than individuals, as they are more salient. We report experimental results on two aerial image datasets, and show that the proposed method is as accurate yet computationally more efficient than standard single-shot detectors, consistently across three different backbone architectures."}],"type":"conference","citation":{"ama":"Royer A, Lampert C.

MEMDPs can be viewed as a special case of Partially observable and Mixed observability MDPs: the state of the system is perfectly observable, but not the environment. We show that the specific structure of MEMDPs allows for more efficient algorithmic analysis, in particular for faster belief updates. We demonstrate the applicability of MEMDPs in several domains.

Here, combining top‐down nanofabrication and bottom‐up self‐assembly, the growth of Ge wires on prepatterned Si (001) substrates with controllable position, distance, length, and structure is reported. This is achieved by a novel growth process that uses a SiGe strain‐relaxation template and can be potentially generalized to other material combinations. Transport measurements show an electrically tunable spin–orbit coupling, with a spin–orbit length similar to that of III–V materials. Also, charge sensing between quantum dots in closely spaced wires is observed, which underlines their potential for the realization of advanced quantum devices. The reported results open a path toward scalable qubit devices using nanowires on silicon."}],"pmid":1,"type":"journal_article","quality_controlled":"1","corr_author":"1","publisher":"Wiley","volume":32,"department":[{"_id":"GeKa"}],"oa_version":"Published Version","language":[{"iso":"eng"}],"status":"public","has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","file_date_updated":"2020-11-20T10:11:35Z","title":"Site-controlled uniform Ge/Si hut wires with electrically tunable spin-orbit coupling","author":[{"last_name":"Gao","full_name":"Gao, Fei","first_name":"Fei"},{"full_name":"Wang, Jian-Huan","last_name":"Wang","first_name":"Jian-Huan"},{"last_name":"Watzinger","full_name":"Watzinger, Hannes","id":"35DF8E50-F248-11E8-B48F-1D18A9856A87","first_name":"Hannes"},{"first_name":"Hao","full_name":"Hu, Hao","last_name":"Hu"},{"last_name":"Rančić","full_name":"Rančić, Marko J.","first_name":"Marko J."},{"first_name":"Jie-Yin","last_name":"Zhang","full_name":"Zhang, Jie-Yin"},{"last_name":"Wang","full_name":"Wang, Ting","first_name":"Ting"},{"last_name":"Yao","full_name":"Yao, Yuan","first_name":"Yuan"},{"last_name":"Wang","full_name":"Wang, Gui-Lei","first_name":"Gui-Lei"},{"first_name":"Josip","last_name":"Kukucka","full_name":"Kukucka, Josip","id":"3F5D8856-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Lada","id":"31E9F056-F248-11E8-B48F-1D18A9856A87","full_name":"Vukušić, Lada","last_name":"Vukušić","orcid":"0000-0003-2424-8636"},{"full_name":"Kloeffel, Christoph","last_name":"Kloeffel","first_name":"Christoph"},{"first_name":"Daniel","last_name":"Loss","full_name":"Loss, Daniel"},{"first_name":"Feng","full_name":"Liu, Feng","last_name":"Liu"},{"first_name":"Georgios","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","full_name":"Katsaros, Georgios","last_name":"Katsaros","orcid":"0000-0001-8342-202X"},{"first_name":"Jian-Jun","last_name":"Zhang","full_name":"Zhang, Jian-Jun"}],"related_material":{"record":[{"status":"public","relation":"other","id":"17444"},{"id":"9222","relation":"research_data","status":"public"},{"relation":"dissertation_contains","id":"7996","status":"public"}]},"date_updated":"2026-04-08T07:27:13Z","article_number":"1906523","acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"}],"acknowledgement":"This work was supported by the National Key R&D Program of China (Grant Nos. 2016YFA0301701 and 2016YFA0300600), the NSFC (Grant Nos. 11574356, 11434010, and 11404252), the Strategic Priority Research Program of CAS (Grant No. XDB30000000), the ERC Starting Grant No. 335497, the FWF P32235 project, and the European Union's Horizon 2020 research and innovation program under Grant Agreement #862046.

This might open the path towards the synthesis of new materials or medical drugs, optimization of transport or financial strategies etc., intractable on even the fastest classical computers. A quantum computer consists of interconnected two level quantum systems, called qubits, that satisfy DiVincezo’s criteria. Worldwide, there are ongoing efforts to find the qubit architecture which will unite quantum error correction compatible single and two qubit fidelities, long distance qubit to qubit coupling and \r\n calability. Superconducting qubits have gone the furthest in this race, demonstrating an algorithm running on 53 coupled qubits, but still the fidelities are not even close to those required for realizing a single logical qubit.  emiconductor qubits offer extremely good characteristics, but they are currently investigated across different platforms. Uniting those good characteristics into a single platform might be a big step towards the quantum computer realization.\r\nHere we describe the implementation of a hole spin qubit hosted in a Ge hut wire double quantum dot. The high and tunable spin-orbit coupling together with a heavy hole state character is expected to allow fast spin manipulation and long coherence times. Furthermore large lever arms, for hut wire devices, should allow good coupling to superconducting resonators enabling efficient long distance spin to spin coupling and a sensitive gate reflectometry spin readout. The developed cryogenic setup (printed circuit board sample holders, filtering, high-frequency wiring) enabled us to perform low temperature spin dynamics experiments. Indeed, we measured the fastest single spin qubit Rabi frequencies reported so far, reaching 140 MHz, while the dephasing times of 130 ns oppose the long decoherence predictions. In order to further investigate this, a double quantum dot gate was connected directly to a lumped element\r\nresonator which enabled gate reflectometry readout. The vanishing inter-dot transition signal, for increasing external magnetic field, revealed the spin nature of the measured quantity."}],"citation":{"short":"J.

Since the density of states typically exhibits only square root or cubic root cusp singularities, our work complements previous results on the bulk and edge universality and it thus completes the resolution of the Wigner–Dyson–Mehta universality conjecture for the last remaining universality type in the complex Hermitian class. Our analysis holds not only for exact cusps, but approximate cusps as well, where an extended Pearcey process emerges. As a main technical ingredient we prove an optimal local law at the cusp for both symmetry classes. This result is also the key input in the companion paper (Cipolloni et al. in Pure Appl Anal, 2018. arXiv:1811.04055) where the cusp universality for real symmetric Wigner-type matrices is proven. The novel cusp fluctuation mechanism is also essential for the recent results on the spectral radius of non-Hermitian random matrices (Alt et al. in Spectral radius of random matrices with independent entries, 2019. arXiv:1907.13631), and the non-Hermitian edge universality (Cipolloni et al. in Edge universality for non-Hermitian random matrices, 2019. arXiv:1908.00969)."}],"citation":{"ama":"Erdös L, Krüger TH, Schröder DJ.

Electro-opto-mechanical devices are currently one of the leading approaches to realize ultra-sensitive, low-loss transducers for an emerging quantum information technology. Here we present an on-chip microwave frequency converter based on a planar aluminum on silicon nitride platform that is compatible with slot-mode coupled photonic crystal cavities. We show efficient frequency conversion between two propagating microwave modes mediated by the radiation pressure interaction with a metalized dielectric nanobeam oscillator. We achieve bidirectional coherent conversion with a total device efficiency of up to ~60%, a dynamic range of 2 × 10^9 photons/s and an instantaneous bandwidth of up to 1.7 kHz. A high fidelity quantum state transfer would be possible if the drive dependent output noise of currently ~14 photons s^−1 Hz^−1 is further reduced. Such a silicon nitride based transducer is in situ reconfigurable and could be used for on-chip classical and quantum signal routing and filtering, both for microwave and hybrid microwave-optical applications.","lang":"eng"}],"citation":{"short":"J.M.

These circuit elements have a characteristic impedance exceeding the resistance quantum RQ ≈ 6.45 kΩ which leads to a suppression of ground state charge fluctuations. Applications include the realization of hardware protected qubits for fault tolerant quantum computing, improved coupling to small dipole moment objects and defining a new quantum metrology standard for the ampere. In this work we refute the widespread notion that superinductors can only be implemented based on kinetic inductance, i.e. using disordered superconductors or Josephson junction arrays. We present modeling, fabrication and characterization of 104 planar aluminum coil resonators with a characteristic impedance up to 30.9 kΩ at 5.6 GHz and a capacitance down to ≤ 1 fF, with lowloss and a power handling reaching 108 intra-cavity photons. Geometric superinductors are free of uncontrolled tunneling events and offer high reproducibility, linearity and the ability to couple magnetically - properties that significantly broaden the scope of future quantum circuits.
