While a certain trait might bring a fitness advantage in some patch of the environment, a different trait might be advantageous in another patch. Here, we study the Moran birth–death process with two types of individuals in a population stretched across two patches of size N, each patch favouring one of the two types. We show that the long-term fate of such populations crucially depends on the migration rate μ\r\n between the patches. To classify the possible fates, we use the distinction between polynomial (short) and exponential (long) timescales. We show that when μ is high then one of the two types fixates on the whole population after a number of steps that is only polynomial in N. By contrast, when μ is low then each type holds majority in the patch where it is favoured for a number of steps that is at least exponential in N. Moreover, we precisely identify the threshold migration rate μ⋆ that separates those two scenarios, thereby exactly delineating the situations that support long-term coexistence of the two types. We also discuss the case of various cycle graphs and we present computer simulations that perfectly match our analytical results.","lang":"eng"}],"oa_version":"Published Version","scopus_import":"1","month":"03","intvolume":" 479","publication_identifier":{"eissn":["1471-2946"],"issn":["1364-5021"]},"publication_status":"published","file":[{"file_name":"2023_ProceedingsRoyalSocietyA_Svoboda.pdf","date_created":"2023-04-03T06:25:29Z","creator":"dernst","file_size":827784,"date_updated":"2023-04-03T06:25:29Z","success":1,"file_id":"12796","checksum":"13953d349fbefcb5d21ccc6b303297eb","relation":"main_file","access_level":"open_access","content_type":"application/pdf"}],"language":[{"iso":"eng"}],"volume":479,"issue":"2271","related_material":{"link":[{"url":"https://doi.org/10.6084/m9.figshare.21261771.v1","relation":"research_data"}]},"license":"https://creativecommons.org/licenses/by/4.0/","ec_funded":1,"article_number":"20220685","project":[{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","grant_number":"863818","name":"Formal Methods for Stochastic Models: Algorithms and Applications"}],"citation":{"mla":"Svoboda, Jakub, et al. “Coexistence Times in the Moran Process with Environmental Heterogeneity.” Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, vol. 479, no. 2271, 20220685, The Royal Society, 2023, doi:10.1098/rspa.2022.0685.","short":"J.

A periodically kicked molecular rotor can be mapped onto a “crystalline” lattice in angular momentum space. This allows us to define quasimomenta and the band structure in the Floquet representation, by analogy with the Bloch waves of solid-state physics. Applying laser pulses spaced by 1/3 of the molecular rotational period creates a lattice with three atoms per unit cell with staggered hopping. Within the synthetic dimension of the laser strength, we discover Dirac cones with topological charges. These Dirac cones, topologically protected by reflection and time-reversal symmetry, are reminiscent of (although not equivalent to) that seen in graphene. They—and the corresponding edge states—are broadly tunable by adjusting the laser strength and can be observed in present-day experiments by measuring molecular alignment and populations of rotational levels.

To this end, we study the density of states of multilayer graphene with up to four layers at the single-particle band structure level in the presence of a transverse electric field. Among the considered structures, tetralayer graphene with rhombohedral (ABCA) stacking reaches the highest density of states. We study the phases that can arise in ABCA graphene by tuning the carrier density and transverse electric field. For a broad region of the tuning parameters, the presence of strong Coulomb repulsion leads to a spontaneous spin and valley symmetry breaking via Stoner transitions. Using a model that incorporates the spontaneous spin and valley polarization, we explore the Kohn-Luttinger mechanism for superconductivity driven by repulsive Coulomb interactions. We find that the strongest superconducting instability is in the p-wave channel, and occurs in proximity to the onset of Stoner transitions. Interestingly, we find a range of densities and transverse electric fields where superconductivity develops out of a strongly corrugated, singly connected Fermi surface in each valley, leading to a topologically nontrivial chiral p+ip superconducting state with an even number of copropagating chiral Majorana edge modes. Our work establishes ABCA-stacked tetralayer graphene as a promising platform for observing strongly correlated physics and topological superconductivity.","lang":"eng"}],"volume":107,"related_material":{"link":[{"url":"https://ista.ac.at/en/news/reaching-superconductivity-layer-by-layer/","relation":"press_release","description":"News on the ISTA website"}]},"issue":"10","language":[{"iso":"eng"}],"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"publication_status":"published"},{"volume":46,"issue":"3","publication_identifier":{"eissn":["1292-895X"],"issn":["1292-8941"]},"publication_status":"published","language":[{"iso":"eng"}],"scopus_import":"1","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.2301.07769","open_access":"1"}],"month":"03","intvolume":" 46","abstract":[{"text":"We investigate the capabilities of Physics-Informed Neural Networks (PINNs) to reconstruct turbulent Rayleigh–Bénard flows using only temperature information.

We reveal the quasiparticle properties, such as energies, quasiparticle weights, and spectral functions, and show that our ansatz yields a persistent decrease in the impurity’s rotational constant due to many-body dressing, which is consistent with experimental observations. From our study, a picture of the angulon emerges as an effective spin interacting with a magnetic field that is self-consistently generated by the molecule’s rotation. Moreover, we discuss rotational spectroscopy, which focuses on the response of rotating molecules to a laser perturbation in the linear response regime. Importantly, we take into account initial-state interactions that have been neglected in prior studies and reveal their impact on the excitation spectrum. To examine the angulon instability regime, we use a single-excitation ansatz and obtain results consistent with experiments, in which a broadening of spectral lines is observed while phonon wings remain highly suppressed due to initial-state interactions."}],"intvolume":" 158","month":"04","scopus_import":"1"},{"volume":13,"issue":"1","ec_funded":1,"publication_identifier":{"eissn":["2160-3308"]},"publication_status":"published","file":[{"content_type":"application/pdf","access_level":"open_access","relation":"main_file","file_id":"12845","checksum":"ee060cea609af79bba7af74b1ce28078","success":1,"date_updated":"2023-04-17T08:36:53Z","file_size":1958523,"creator":"dernst","date_created":"2023-04-17T08:36:53Z","file_name":"2023_PhysReviewX_Ljubotina.pdf"}],"language":[{"iso":"eng"}],"scopus_import":"1","month":"03","intvolume":" 13","abstract":[{"text":"Universal nonequilibrium properties of isolated quantum systems are typically probed by studying transport of conserved quantities, such as charge or spin, while transport of energy has received considerably less attention. Here, we study infinite-temperature energy transport in the kinetically constrained PXP model describing Rydberg atom quantum simulators. Our state-of-the-art numerical simulations, including exact diagonalization and time-evolving block decimation methods, reveal the existence of two distinct transport regimes. At moderate times, the energy-energy correlation function displays periodic oscillations due to families of eigenstates forming different su(2) representations hidden within the spectrum. These families of eigenstates generalize the quantum many-body scarred states found in previous works and leave an imprint on the infinite-temperature energy transport. At later times, we observe a long-lived superdiffusive transport regime that we attribute to the proximity of a nearby integrable point. While generic strong deformations of the PXP model indeed restore diffusive transport, adding a strong chemical potential intriguingly gives rise to a well-converged superdiffusive exponent z≈3/2. Our results suggest constrained models to be potential hosts of novel transport regimes and call for developing an analytic understanding of their energy transport.","lang":"eng"}],"oa_version":"Published Version","file_date_updated":"2023-04-17T08:36:53Z","department":[{"_id":"MaSe"}],"date_updated":"2023-08-01T14:11:28Z","ddc":["530"],"type":"journal_article","article_type":"original","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)"},"status":"public","_id":"12839","doi":"10.1103/PhysRevX.13.011033","date_published":"2023-03-07T00:00:00Z","date_created":"2023-04-16T22:01:09Z","isi":1,"has_accepted_license":"1","year":"2023","day":"07","publication":"Physical Review X","publisher":"American Physical Society","quality_controlled":"1","oa":1,"acknowledgement":"We would like to thank Alexios Michailidis, Sarang Gopalakrishnan, and Achilleas Lazarides for useful comments.

Such catalysts must contain multiple adsorption/reaction sites to cope with the high demands of reversible oxygen electrodes. Herein, we propose a high entropy alloy (HEA) based on relatively abundant elements as a bifunctional ORR/OER catalyst. More specifically, we detail the synthesis of a CrMnFeCoNi HEA through a low-temperature solution-based approach. Such HEA displays superior OER performance with an overpotential of 265 mV at a current density of 10 mA/cm2, and a 37.9 mV/dec Tafel slope, well above the properties of a standard commercial catalyst based on RuO2. This high performance is partially explained by the presence of twinned defects, the incidence of large lattice distortions, and the electronic synergy between the different components, being Cr key to decreasing the energy barrier of the OER rate-determining step. CrMnFeCoNi also displays superior ORR performance with a half-potential of 0.78 V and an onset potential of 0.88 V, comparable with commercial Pt/C. The potential gap (Egap) between the OER overpotential and the ORR half-potential of CrMnFeCoNi is just 0.734 V. Taking advantage of these outstanding properties, ZABs are assembled using the CrMnFeCoNi HEA as air cathode and a zinc foil as the anode. The assembled cells provide an open-circuit voltage of 1.489 V, i.e. 90% of its theoretical limit (1.66 V), a peak power density of 116.5 mW/cm2, and a specific capacity of 836 mAh/g that stays stable for more than 10 days of continuous cycling, i.e. 720 cycles @ 8 mA/cm2 and 16.6 days of continuous cycling, i.e. 1200 cycles @ 5 mA/cm2."}],"oa_version":"None","department":[{"_id":"MaIb"}],"date_updated":"2023-08-01T14:08:02Z","type":"journal_article","article_type":"original","status":"public","_id":"12832"},{"year":"2023","has_accepted_license":"1","isi":1,"publication":"Advanced Intelligent Systems","day":"01","date_created":"2023-04-12T08:30:03Z","date_published":"2023-01-01T00:00:00Z","doi":"10.1002/aisy.202200129","acknowledgement":"Army Research Office.

They restrain degrees of freedom and channel power into a specified motion. Building and powering small-scale cogwheels are key steps toward feasible micro and nanomachinery. Assembly, energy injection, and control are, however, a challenge at the microscale. In contrast with passive gears, whose function is to transmit torques from one to another, interlocking and untethered active gears have the potential to unveil dynamics and functions untapped by externally driven mechanisms. Here, it is shown the assembly and control of a family of self-spinning cogwheels with varying teeth numbers and study the interlocking of multiple cogwheels. The teeth are formed by colloidal microswimmers that power the structure. The cogwheels are autonomous and active, showing persistent rotation. Leveraging the angular momentum of optical vortices, we control the direction of rotation of the cogwheels. The pairs of interlocking and active cogwheels that roll over each other in a random walk and have curvature-dependent mobility are studied. This behavior is leveraged to self-position parts and program microbots, demonstrating the ability to pick up, direct, and release a load. The work constitutes a step toward autonomous machinery with external control as well as (re)programmable microbots and matter."}],"oa_version":"Published Version","intvolume":" 5","month":"01","date_updated":"2023-08-01T14:06:50Z","ddc":["530"],"file_date_updated":"2023-04-17T06:44:17Z","department":[{"_id":"JePa"}],"_id":"12822","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)"},"article_type":"original","type":"journal_article","status":"public"},{"oa":1,"publisher":"Springer Nature","quality_controlled":"1","acknowledgement":"We thank H.

In these settings, cells establish supracellular patterns of motion, including collective rotation and invasion. While such collective modes have been studied extensively in flat systems, the consequences of geometrical and topological constraints on collective migration in curved systems are largely unknown. Here, we discover a collective mode of cell migration in rotating spherical tissues manifesting as a propagating single-wavelength velocity wave. This wave is accompanied by an apparently incompressible supracellular flow pattern featuring topological defects as dictated by the spherical topology. Using a minimal active particle model, we reveal that this collective mode arises from the effect of curvature on the active flocking behavior of a cell layer confined to a spherical surface. Our results thus identify curvature-induced velocity waves as a mode of collective cell migration, impacting the dynamical organization of 3D curved tissues."}],"volume":14,"language":[{"iso":"eng"}],"file":[{"creator":"dernst","date_updated":"2023-04-11T06:27:00Z","file_size":4146777,"date_created":"2023-04-11T06:27:00Z","file_name":"2023_NatureComm_Brandstaetter.pdf","access_level":"open_access","relation":"main_file","content_type":"application/pdf","checksum":"54f06f9eee11d43bab253f3492c983ba","file_id":"12821","success":1}],"publication_status":"published","publication_identifier":{"eissn":["2041-1723"]},"status":"public","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)"},"type":"journal_article","article_type":"original","_id":"12818","department":[{"_id":"EdHa"}],"file_date_updated":"2023-04-11T06:27:00Z","ddc":["570"],"date_updated":"2023-08-01T14:05:30Z"}]
