Here, we propose a coherent state ansatz in the co-rotating frame, which provides a comprehensive theoretical description of angulons. 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.","lang":"eng"}],"oa_version":"Published Version","ec_funded":1,"volume":158,"issue":"13","publication_status":"published","publication_identifier":{"eissn":["1089-7690"]},"language":[{"iso":"eng"}],"file":[{"success":1,"checksum":"8d801babea4df48e08895c76571bb19e","file_id":"12841","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_name":"2023_JourChemicalPhysics_Zeng.pdf","date_created":"2023-04-17T07:28:38Z","file_size":7388057,"date_updated":"2023-04-17T07:28:38Z","creator":"dernst"}]},{"article_number":"011033","project":[{"name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control","grant_number":"850899","call_identifier":"H2020","_id":"23841C26-32DE-11EA-91FC-C7463DDC885E"}],"citation":{"ama":"Ljubotina M, Desaules JY, Serbyn M, Papić Z.

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."}],"oa_version":"Published Version","scopus_import":"1","intvolume":" 13","month":"03","publication_status":"published","publication_identifier":{"eissn":["2160-3308"]},"language":[{"iso":"eng"}],"file":[{"relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"checksum":"ee060cea609af79bba7af74b1ce28078","file_id":"12845","creator":"dernst","file_size":1958523,"date_updated":"2023-04-17T08:36:53Z","file_name":"2023_PhysReviewX_Ljubotina.pdf","date_created":"2023-04-17T08:36:53Z"}],"ec_funded":1,"volume":13,"issue":"1"},{"scopus_import":"1","month":"04","intvolume":" 58","acknowledged_ssus":[{"_id":"EM-Fac"}],"abstract":[{"lang":"eng","text":"The development of cost-effective, high-activity and stable bifunctional catalysts for the oxygen reduction and evolution reactions (ORR/OER) is essential for zinc–air batteries (ZABs) to reach the market. 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","issue":"4","volume":58,"publication_identifier":{"eissn":["2405-8297"]},"publication_status":"published","language":[{"iso":"eng"}],"article_type":"original","type":"journal_article","status":"public","_id":"12832","department":[{"_id":"MaIb"}],"date_updated":"2023-08-01T14:08:02Z","publisher":"Elsevier","quality_controlled":"1","acknowledgement":"The authors thank the support from the project COMBENERGY, PID2019-105490RB-C32, from the Spanish Ministerio de Ciencia e Innovación.

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.","lang":"eng"}],"month":"01","intvolume":" 5","file":[{"checksum":"d48fc41d39892e7fa0d44cb352dd46aa","file_id":"12840","success":1,"access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2023-04-17T06:44:17Z","file_name":"2023_AdvancedIntelligentSystems_Martinet.pdf","creator":"dernst","date_updated":"2023-04-17T06:44:17Z","file_size":2414125}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2640-4567"]},"publication_status":"published","volume":5,"issue":"1"},{"article_number":"1643","title":"Curvature induces active velocity waves in rotating spherical tissues","external_id":{"pmid":["36964141"],"isi":["000959887700008"]},"article_processing_charge":"No","author":[{"last_name":"Brandstätter","full_name":"Brandstätter, Tom","first_name":"Tom"},{"id":"e1e86031-6537-11eb-953a-f7ab92be508d","first_name":"David","last_name":"Brückner","full_name":"Brückner, David","orcid":"0000-0001-7205-2975"},{"full_name":"Han, Yu Long","last_name":"Han","first_name":"Yu Long"},{"full_name":"Alert, Ricard","last_name":"Alert","first_name":"Ricard"},{"first_name":"Ming","last_name":"Guo","full_name":"Guo, Ming"},{"full_name":"Broedersz, Chase P.","last_name":"Broedersz","first_name":"Chase P."}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"chicago":"Brandstätter, Tom, David Brückner, Yu Long Han, Ricard Alert, Ming Guo, and Chase P.

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":[{"success":1,"file_id":"12821","checksum":"54f06f9eee11d43bab253f3492c983ba","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_name":"2023_NatureComm_Brandstaetter.pdf","date_created":"2023-04-11T06:27:00Z","file_size":4146777,"date_updated":"2023-04-11T06:27:00Z","creator":"dernst"}],"publication_status":"published","publication_identifier":{"eissn":["2041-1723"]}}]
