This material combination leads to spatial variations of the superconducting properties, which gives rise to Andreev bound states (ABSs). Some of these states might exhibit remarkable properties that render them highly desirable for topological quantum computing. The most prominent and hunted of such states are Majorana zero modes (MZMs), quasiparticles equals to their own quasiparticles that they follow non-abelian statistics. In this thesis, we first introduce the general framework of such hybrid systems and, then, we unveil a series of mesoscopic phenomena that we discovered. Firstly, we show tunneling spectroscopy experiments on full-shell nanowires (NWs) showing that unwanted quantum-dot states coupled to superconductors (Yu-Shiba-Rusinov states) can mimic MZMs signatures. Then, we introduce a novel protocol which allowed the integration of tunneling spectroscopy with Coulomb spectroscopy within the same device. Employing this approach on both full-shell NWs and partial-shell NWs, we demonstrated that longitudinally confined states reveal charge transport phenomenology similar to the one expected for MZMs. These findings shed light on the intricate interplay between superconductivity and quantum confinement, which brought us to explore another material platform, i.e. a two-dimensional Germanium hole gas. After developing a robust way to induce superconductivity in such system, we showed how to engineer the proximity effect and we revealed a superconducting hard gap. Finally, we created a superconducting radio frequency driven ideal diode and a generator of non-sinusoidal current-phase relations. Our results open the path for the exploration of protected superconducting qubits and more complex hybrid devices in planar Germanium, like Kitaev chains and hybrid qubit devices.","lang":"eng"}],"tmp":{"short":"CC BY-NC-SA (4.0)","image":"/images/cc_by_nc_sa.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)"},"acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"}],"doi":"10.15479/at:ista:13286","oa_version":"Published Version","type":"dissertation","day":"21","citation":{"apa":"Valentini, M.

This includes the decidability of language inclusion, which is the ultimate verification problem. Operator precedence grammars, automata, and logics have been investigated and used, for example, to verify programs with arithmetic expressions and exceptions (both of which are deterministic pushdown but lie outside the scope of the visibly pushdown languages). In this paper, we complete the picture and give, for the first time, an algebraic characterization of the class of OPLs in the form of a syntactic congruence that has finitely many equivalence classes exactly for the operator precedence languages. This is a generalization of the celebrated Myhill-Nerode theorem for the regular languages to OPLs. As one of the consequences, we show that universality and language inclusion for nondeterministic operator precedence automata can be solved by an antichain algorithm. Antichain algorithms avoid determinization and complementation through an explicit subset construction, by leveraging a quasi-order on words, which allows the pruning of the search space for counterexample words without sacrificing completeness. Antichain algorithms can be implemented symbolically, and these implementations are today the best-performing algorithms in practice for the inclusion of finite automata. We give a generic construction of the quasi-order needed for antichain algorithms from a finite syntactic congruence. This yields the first antichain algorithm for OPLs, an algorithm that solves the ExpTime-hard language inclusion problem for OPLs in exponential time."}],"volume":261,"doi":"10.4230/LIPIcs.ICALP.2023.129","quality_controlled":"1","oa_version":"Published Version","type":"conference","day":"05","citation":{"apa":"Henzinger, T.

We present runtime verification of algorithmic fairness for systems whose models are unknown, but are assumed to have a Markov chain structure. We introduce a specification language that can model many common algorithmic fairness properties, such as demographic parity, equal opportunity, and social burden. We build monitors that observe a long sequence of events as generated by a given system, and output, after each observation, a quantitative estimate of how fair or biased the system was on that run until that point in time. The estimate is proven to be correct modulo a variable error bound and a given confidence level, where the error bound gets tighter as the observed sequence gets longer. Our monitors are of two types, and use, respectively, frequentist and Bayesian statistical inference techniques. While the frequentist monitors compute estimates that are objectively correct with respect to the ground truth, the Bayesian monitors compute estimates that are correct subject to a given prior belief about the system’s model. Using a prototype implementation, we show how we can monitor if a bank is fair in giving loans to applicants from different social backgrounds, and if a college is fair in admitting students while maintaining a reasonable financial burden on the society. Although they exhibit different theoretical complexities in certain cases, in our experiments, both frequentist and Bayesian monitors took less than a millisecond to update their verdicts after each observation.","lang":"eng"}],"volume":13965,"doi":"10.1007/978-3-031-37703-7_17","quality_controlled":"1","oa_version":"Published Version","day":"18","type":"conference","citation":{"mla":"Henzinger, Thomas A., et al. “Monitoring Algorithmic Fairness.” Computer Aided Verification, vol. 13965, Springer Nature, 2023, pp. 358–382, doi:10.1007/978-3-031-37703-7_17.","short":"T.A.

During bacterial cell division, FtsZ—a prokaryotic homologue of the eukaryotic protein tubulin—polymerizes into treadmilling filaments that further organize into a cytoskeletal ring. In vitro, FtsZ filaments can form dynamic chiral assemblies. However, how the active and passive properties of individual filaments relate to these large-scale self-organized structures remains poorly understood. Here we connect single-filament properties with the mesoscopic scale by combining minimal active matter simulations and biochemical reconstitution experiments. We show that the density and flexibility of active chiral filaments define their global order. At intermediate densities, curved, flexible filaments organize into chiral rings and polar bands. An effectively nematic organization dominates for high densities and for straight, mutant filaments with increased rigidity. Our predicted phase diagram quantitatively captures these features, demonstrating how the flexibility, density and chirality of the active filaments affect their collective behaviour. Our findings shed light on the fundamental properties of active chiral matter and explain how treadmilling FtsZ filaments organize during bacterial cell division.","lang":"eng"}],"tmp":{"short":"CC BY (4.0)","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)"},"acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"volume":19,"title":"Chiral and nematic phases of flexible active filaments","scopus_import":"1","language":[{"iso":"eng"}],"date_created":"2023-07-27T14:44:45Z","department":[{"_id":"JoDa"},{"_id":"EdHa"},{"_id":"MaLo"},{"_id":"GradSch"}],"day":"01","type":"journal_article","related_material":{"record":[{"id":"13116","status":"public","relation":"research_data"}]},"citation":{"mla":"Dunajova, Zuzana, et al. “Chiral and Nematic Phases of Flexible Active Filaments.” Nature Physics, vol. 19, Springer Nature, 2023, pp. 1916–26, doi:10.1038/s41567-023-02218-w.","apa":"Dunajova, Z., Prats Mateu, B., Radler, P., Lim, K., Brandis, D., Velicky, P., … Loose, M.

To answer this, we study the paradigmatic spiked matrix model of principal components analysis (PCA), where a rank-one matrix is corrupted by additive noise. We go beyond the usual independence assumption on the noise entries, by drawing the noise from a low-order polynomial orthogonal matrix ensemble. The resulting noise correlations make the setting relevant for applications but analytically challenging. We provide characterization of the Bayes optimal limits of inference in this model. If the spike is rotation invariant, we show that standard spectral PCA is optimal. However, for more general priors, both PCA and the existing approximate message-passing algorithm (AMP) fall short of achieving the information-theoretic limits, which we compute using the replica method from statistical physics. We thus propose an AMP, inspired by the theory of adaptive Thouless–Anderson–Palmer equations, which is empirically observed to saturate the conjectured theoretical limit. This AMP comes with a rigorous state evolution analysis tracking its performance. Although we focus on specific noise distributions, our methodology can be generalized to a wide class of trace matrix ensembles at the cost of more involved expressions. Finally, despite the seemingly strong assumption of rotation-invariant noise, our theory empirically predicts algorithmic performance on real data, pointing at strong universality properties."}],"article_type":"original","article_number":"e2302028120","issue":"30","intvolume":" 120","date_created":"2023-07-30T22:01:02Z","language":[{"iso":"eng"}],"department":[{"_id":"MaMo"}],"scopus_import":"1","title":"Fundamental limits in structured principal component analysis and how to reach them"},{"_id":"13316","publication_status":"published","date_updated":"2023-12-13T11:37:36Z","year":"2023","publication_identifier":{"eissn":["2050-084X"]},"ddc":["570"],"date_published":"2023-07-21T00:00:00Z","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"Yes","oa":1,"external_id":{"pmid":["37477116"],"isi":["001035372800001"]},"author":[{"last_name":"Toshima","full_name":"Toshima, Junko Y.","first_name":"Junko Y."},{"first_name":"Ayana","full_name":"Tsukahara, Ayana","last_name":"Tsukahara"},{"first_name":"Makoto","full_name":"Nagano, Makoto","last_name":"Nagano"},{"last_name":"Tojima","first_name":"Takuro","full_name":"Tojima, Takuro"},{"full_name":"Siekhaus, Daria E","first_name":"Daria E","orcid":"0000-0001-8323-8353","id":"3D224B9E-F248-11E8-B48F-1D18A9856A87","last_name":"Siekhaus"},{"first_name":"Akihiko","full_name":"Nakano, Akihiko","last_name":"Nakano"},{"last_name":"Toshima","full_name":"Toshima, Jiro","first_name":"Jiro"}],"isi":1,"acknowledgement":"This work was supported by JSPS KAKENHI grant #18K062291, and the Takeda Science Foundation to JYT., as well as JSPS KAKENHI grant #19K065710, the Takeda Science Foundation, and Life Science Foundation of Japan to JT.","file":[{"success":1,"relation":"main_file","content_type":"application/pdf","checksum":"2af111a00cf5e3a956f7f0fd13199b15","file_size":11980913,"file_name":"2023_eLife_Toshima.pdf","date_created":"2023-07-31T07:43:00Z","file_id":"13324","date_updated":"2023-07-31T07:43:00Z","creator":"dernst","access_level":"open_access"}],"month":"07","pmid":1,"publication":"eLife","file_date_updated":"2023-07-31T07:43:00Z","publisher":"eLife Sciences Publications","has_accepted_license":"1","date_created":"2023-07-30T22:01:02Z","language":[{"iso":"eng"}],"department":[{"_id":"DaSi"}],"scopus_import":"1","title":"The yeast endocytic early/sorting compartment exists as an independent sub-compartment within the trans-Golgi network","volume":12,"tmp":{"short":"CC BY (4.0)","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)"},"abstract":[{"lang":"eng","text":"Although budding yeast has been extensively used as a model organism for studying organelle functions and intracellular vesicle trafficking, whether it possesses an independent endocytic early/sorting compartment that sorts endocytic cargos to the endo-lysosomal pathway or the recycling pathway has long been unclear. The structure and properties of the endocytic early/sorting compartment differ significantly between organisms; in plant cells, the trans-Golgi network (TGN) serves this role, whereas in mammalian cells a separate intracellular structure performs this function. The yeast syntaxin homolog Tlg2p, widely localizing to the TGN and endosomal compartments, is presumed to act as a Q-SNARE for endocytic vesicles, but which compartment is the direct target for endocytic vesicles remained unanswered. Here we demonstrate by high-speed and high-resolution 4D imaging of fluorescently labeled endocytic cargos that the Tlg2p-residing compartment within the TGN functions as the early/sorting compartment. After arriving here, endocytic cargos are recycled to the plasma membrane or transported to the yeast Rab5-residing endosomal compartment through the pathway requiring the clathrin adaptors GGAs. Interestingly, Gga2p predominantly localizes at the Tlg2p-residing compartment, and the deletion of GGAs has little effect on another TGN region where Sec7p is present but suppresses dynamics of the Tlg2-residing early/sorting compartment, indicating that the Tlg2p- and Sec7p-residing regions are discrete entities in the mutant. Thus, the Tlg2p-residing region seems to serve as an early/sorting compartment and function independently of the Sec7p-residing region within the TGN."}],"article_number":"e84850","article_type":"original","intvolume":" 12","oa_version":"Published Version","doi":"10.7554/eLife.84850","quality_controlled":"1","day":"21","type":"journal_article","citation":{"apa":"Toshima, J.

Motivated by learning quantum observables, a qubit analogue of Bohnenblust–Hille inequality for Boolean cubes was recently conjectured in Rouzé et al. (Quantum Talagrand, KKL and Friedgut’s theorems and the learnability of quantum Boolean functions, 2022. arXiv preprint arXiv:2209.07279). The conjecture was resolved in Huang et al. (Learning to predict arbitrary quantum processes, 2022. arXiv preprint arXiv:2210.14894). In this paper, we give a new proof of these Bohnenblust–Hille inequalities for qubit system with constants that are dimension-free and of exponential growth in the degree. As a consequence, we obtain a junta theorem for low-degree polynomials. Using similar ideas, we also study learning problems of low degree quantum observables and Bohr’s radius phenomenon on quantum Boolean cubes.","lang":"eng"}],"doi":"10.1007/s00208-023-02680-0","quality_controlled":"1","oa_version":"Published Version","main_file_link":[{"url":"https://doi.org/10.1007/s00208-023-02680-0","open_access":"1"}],"citation":{"ieee":"A.

The multi-layer structure models inference from deep generative priors, and the rotational invariance imposed on the weights generalizes the i.i.d. Gaussian assumption by allowing for a complex correlation structure, which is typical in applications. In this work, we present a new class of approximate message passing (AMP) algorithms and give a state evolution recursion which precisely characterizes their performance in the large system limit. In contrast with the existing multi-layer VAMP (ML-VAMP) approach, our proposed AMP – dubbed multilayer rotationally invariant generalized AMP (ML-RI-GAMP) – provides a natural generalization beyond Gaussian designs, in the sense that it recovers the existing Gaussian AMP as a special case. Furthermore, ML-RI-GAMP exhibits a significantly lower complexity than ML-VAMP, as the computationally intensive singular value decomposition is replaced by an estimation of the moments of the design matrices. Finally, our numerical results show that this complexity gain comes at little to no cost in the performance of the algorithm."}],"oa_version":"Preprint","quality_controlled":"1","doi":"10.1109/ITW55543.2023.10160238","type":"conference","day":"01","citation":{"ama":"Xu Y, Hou TQ, Liang SS, Mondelli M.

However, this reaction typically requires ultraviolet light, which limits applicability. In this study, we introduce disequilibration by sensitization under confinement (DESC), a supramolecular approach to induce the E-to-Z isomerization by using light of a desired color, including red. DESC relies on a combination of a macrocyclic host and a photosensitizer, which act together to selectively bind and sensitize E-azobenzenes for isomerization. The Z isomer lacks strong affinity for and is expelled from the host, which can then convert additional E-azobenzenes to the Z state. In this way, the host–photosensitizer complex converts photon energy into chemical energy in the form of out-of-equilibrium photostationary states, including ones that cannot be accessed through direct photoexcitation.","lang":"eng"}],"article_type":"original","issue":"6664","intvolume":" 381","oa_version":"Preprint","doi":"10.1126/science.adh9059","quality_controlled":"1","citation":{"mla":"Gemen, Julius, et al. “Disequilibrating Azoarenes by Visible-Light Sensitization under Confinement.” Science, vol. 381, no. 6664, American Association for the Advancement of Science, 2023, pp. 1357–63, doi:10.1126/science.adh9059.","short":"J.

While ages are usually computed from stellar evolution models, relations linking ages to other stellar properties, such as rotation and magnetic activity, have been investigated. With the large catalog of 55,232 rotation periods, Prot, and photometric magnetic activity index, Sph from Kepler data, we have the opportunity to look for such magneto-gyro-chronology relations. Stellar ages are obtained with two stellar evolution codes that include treatment of angular momentum evolution, hence using Prot as input in addition to classical atmospheric parameters. We explore two different ways of predicting stellar ages on three subsamples with spectroscopic observations: solar analogs, late-F and G dwarfs, and K dwarfs. We first perform a Bayesian analysis to derive relations between Sph and ages between 1 and 5 Gyr, and other stellar properties. For late-F and G dwarfs, and K dwarfs, the multivariate regression favors the model with Prot and Sph with median differences of 0.1% and 0.2%, respectively. We also apply Machine Learning techniques with a Random Forest algorithm to predict ages up to 14 Gyr with the same set of input parameters. For late-F, G and K dwarfs together, predicted ages are on average within 5.3% of the model ages and improve to 3.1% when including Prot.

Red giant asteroseismology is a prime example, with oscillation periods and amplitudes that are readily detectable with time-domain space-based telescopes. These oscillations can be used to infer masses, ages and radii for large numbers of stars, providing unique constraints on stellar populations in our galaxy. The cadence, duration, and spatial resolution of the Roman galactic bulge time-domain survey (GBTDS) are well-suited for asteroseismology and will probe an important population not studied by prior missions. We identify photometric precision as a key requirement for realizing the potential of asteroseismology with Roman. A precision of 1 mmag per 15-min cadence or better for saturated stars will enable detections of the populous red clump star population in the Galactic bulge. If the survey efficiency is better than expected, we argue for repeat observations of the same fields to improve photometric precision, or covering additional fields to expand the stellar population reach if the photometric precision for saturated stars is better than 1 mmag. Asteroseismology is relatively insensitive to the timing of the observations during the mission, and the prime red clump targets can be observed in a single 70 day campaign in any given field. Complementary stellar characterization, particularly astrometry tied to the Gaia system, will also dramatically expand the diagnostic power of asteroseismology. We also highlight synergies to Roman GBTDS exoplanet science using transits and microlensing."}],"year":"2023","article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Asteroseismology with the Roman galactic bulge time-domain survey","publication_status":"submitted","date_updated":"2023-08-02T07:36:00Z","arxiv":1,"_id":"13447","language":[{"iso":"eng"}],"date_created":"2023-08-02T07:30:43Z","department":[{"_id":"LiBu"}]},{"publication":"Physical Review B","month":"08","file":[{"creator":"dernst","date_updated":"2023-08-07T09:48:08Z","access_level":"open_access","file_id":"13981","file_name":"2023_PhysRevB_Brighi.pdf","date_created":"2023-08-07T09:48:08Z","checksum":"f763000339b5fd543c14377109920690","file_size":3051398,"success":1,"content_type":"application/pdf","relation":"main_file"}],"publisher":"American Physical Society","has_accepted_license":"1","file_date_updated":"2023-08-07T09:48:08Z","date_updated":"2023-08-07T09:51:39Z","project":[{"call_identifier":"H2020","grant_number":"850899","_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control"}],"publication_status":"published","ec_funded":1,"arxiv":1,"_id":"13963","acknowledgement":"We thank A.

The interplay of thermal and nonergodic behavior in these systems gives rise to a rich phase diagram, whose exploration is an active field of research. In this paper, we study a bosonic Hubbard model featuring two particle species representing the bath and the disordered system. Using state-of-the-art numerical techniques, we investigate the dynamics of the model in different regimes, based on which we obtain a tentative phase diagram as a function of coupling strength and bath size. When the bath is composed of a single particle, we observe clear signatures of a transition from an MBL proximity effect to a delocalized phase. Increasing the bath size, however, its thermalizing effect becomes stronger and eventually the whole system delocalizes in the range of moderate interaction strengths studied. In this regime, we characterize particle transport, revealing diffusive behavior of the originally localized bosons.","lang":"eng"}]},{"date_updated":"2023-12-13T12:05:31Z","_id":"13965","oa":1,"external_id":{"pmid":["37441873"],"isi":["001047020200001"]},"author":[{"id":"b8c4f54b-e484-11eb-8fdc-a54df64ef6dd","last_name":"Hollwey","full_name":"Hollwey, Elizabeth","first_name":"Elizabeth"},{"last_name":"Briffa","full_name":"Briffa, Amy","first_name":"Amy"},{"last_name":"Howard","full_name":"Howard, Martin","first_name":"Martin"},{"last_name":"Zilberman","id":"6973db13-dd5f-11ea-814e-b3e5455e9ed1","orcid":"0000-0002-0123-8649","full_name":"Zilberman, Daniel","first_name":"Daniel"}],"isi":1,"status":"public","ddc":["570"],"date_published":"2023-08-01T00:00:00Z","year":"2023","publication_identifier":{"issn":["0959-437X"],"eissn":["1879-0380"]},"article_processing_charge":"Yes (via OA deal)","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","pmid":1,"publication":"Current Opinion in Genetics and Development","file":[{"checksum":"a294cd9506b80ed6ef218ef44ed32765","file_size":2568632,"success":1,"relation":"main_file","content_type":"application/pdf","file_id":"13980","date_updated":"2023-08-07T08:32:26Z","creator":"dernst","access_level":"open_access","date_created":"2023-08-07T08:32:26Z","file_name":"2023_CurrentOpinionGenetics_Hollwey.pdf"}],"month":"08","has_accepted_license":"1","publisher":"Elsevier","file_date_updated":"2023-08-07T08:32:26Z","title":"Concepts, mechanisms and implications of long-term epigenetic inheritance","scopus_import":"1","language":[{"iso":"eng"}],"date_created":"2023-08-06T22:01:10Z","department":[{"_id":"DaZi"}],"intvolume":" 81","article_type":"original","issue":"8","article_number":"102087","tmp":{"short":"CC BY (4.0)","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)"},"abstract":[{"text":"Many modes and mechanisms of epigenetic inheritance have been elucidated in eukaryotes. Most of them are relatively short-term, generally not exceeding one or a few organismal generations. However, emerging evidence indicates that one mechanism, cytosine DNA methylation, can mediate epigenetic inheritance over much longer timescales, which are mostly or completely inaccessible in the laboratory. Here we discuss the evidence for, and mechanisms and implications of, such long-term epigenetic inheritance. We argue that compelling evidence supports the long-term epigenetic inheritance of gene body methylation, at least in the model angiosperm Arabidopsis thaliana, and that variation in such methylation can therefore serve as an epigenetic basis for phenotypic variation in natural populations.","lang":"eng"}],"volume":81,"quality_controlled":"1","doi":"10.1016/j.gde.2023.102087","oa_version":"Published Version","day":"01","type":"journal_article","citation":{"mla":"Hollwey, Elizabeth, et al. “Concepts, Mechanisms and Implications of Long-Term Epigenetic Inheritance.” Current Opinion in Genetics and Development, vol. 81, no. 8, 102087, Elsevier, 2023, doi:10.1016/j.gde.2023.102087.","chicago":"Hollwey, Elizabeth, Amy Briffa, Martin Howard, and Daniel Zilberman. “Concepts, Mechanisms and Implications of Long-Term Epigenetic Inheritance.” Current Opinion in Genetics and Development.
