Within a Bogoliubov–de Gennes tight-binding framework, a superconducting-normal-superconducting (SNS) junction functionalized by adsorbed chiral molecules is modeled, where electrostatic gradients generated by the molecules induce spin-orbit coupling in the normal region. The equilibrium charge current-phase relation is found to remain largely insensitive to molecular chirality in symmetric, zero-field configurations. In contrast, the spin-polarized equilibrium current exhibits a pronounced chirality-dependent response, with opposite enantiomers producing distinct and anisotropic spin-polarized Josephson currents. The resulting handedness contrast can be enhanced through control parameters such as molecular orientation and the strength of the induced spin-orbit coupling. The temperature dependence of these currents further shows that the chirality-dependent signatures persist across a range of temperatures well below the superconducting critical temperature. These results identify Josephson interferometry as a phase-sensitive setting for probing chirality-dependent spin structure and highlight spin-polarized superconducting transport as a controlled route toward integrating chiral molecular functionality into superconducting spintronic devices."}],"file_date_updated":"2026-10-06T13:19:31Z","file":[{"access_level":"open_access","success":1,"date_updated":"2026-10-06T13:19:31Z","file_size":645485,"relation":"main_file","file_id":"23066","creator":"dernst","file_name":"2026_PhysicalReviewB_Kuliashov.pdf","checksum":"784eb7e99c17ecacff5d69c7faf857b6","date_created":"2026-10-06T13:19:31Z","content_type":"application/pdf"}],"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"citation":{"short":"O.

In this work, we consider a long JJ chain that effectively realizes a multimode cavity with nonlinear dispersion and additional multimode interactions. Individual modes appearing due to the finite size of the chain can be experimentally probed via microwave spectroscopy, both in equilibrium and in driven far-from-equilibrium settings. We study the role of multimode interactions in degrading internal coherence—observable as excess linewidth—in both equilibrium and driven regimes. Focusing on two-into-two mode scattering as the leading relaxation process, we classify the relevant scattering processes and derive their expected temperature- and frequency-scaling under equilibrium conditions. For experimentally relevant parameters, we show that the equilibrium decay rate is dominated by nonresonant processes, however, weakly driving a particular set of modes out of equilibrium enhances resonant scattering, leading to observable signatures in the distribution function and linewidth. Finally, in the strong nonequilibrium regime, we report a crossover to a qualitatively different nonequilibrium steady state.","lang":"eng"}],"article_type":"original","day":"01","scopus_import":"1","researchdata_availability":"yes","project":[{"_id":"34a7f947-11ca-11ed-8bc3-c5dc2bbaae25","grant_number":"F8609","name":"Center for Correlated Quantum Materials and Solid State Quantum Systems: Probing topology in circuits and quantum materials"}],"publication":"Physical Review B","ddc":["530"]},{"oa":1,"author":[{"first_name":"Devendra Singh","last_name":"Bhakuni","full_name":"Bhakuni, Devendra Singh"},{"full_name":"Verdel, Roberto","last_name":"Verdel","first_name":"Roberto"},{"full_name":"Desaules, Jean-Yves Marc","last_name":"Desaules","orcid":"0000-0002-3749-6375","id":"6c292945-a610-11ed-9eec-c3be1ad62a80","first_name":"Jean-Yves Marc"},{"orcid":"0000-0002-2399-5827","first_name":"Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","full_name":"Serbyn, Maksym","last_name":"Serbyn"},{"last_name":"Ljubotina","full_name":"Ljubotina, Marko","id":"F75EE9BE-5C90-11EA-905D-16643DDC885E","first_name":"Marko","orcid":"0000-0003-0038-7068"},{"full_name":"Dalmonte, Marcello","last_name":"Dalmonte","first_name":"Marcello"}],"intvolume":" 114","publisher":"American Physical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","status":"public","doi":"10.1103/3371-88bl","year":"2026","title":"Anomalously fast transport in nonintegrable lattice gauge theories","date_updated":"2026-10-07T09:29:50Z","_id":"23027","article_number":"L140103","dataavailabilitystatement":"There are no publicly available research\r\ndata or software supporting this manuscript.

The damping time\r\nτ , which separates the short-time magnon-dominated behavior from the late-time hydrodynamics, grows rapidly\r\nupon cooling, consistent with an activated form τ (β) ∼ βe\u0005β with a gap scale set by the magnon band. At longer\r\ntimes, the spectral weight transfers to q = 0 and the running decay exponent drifts toward the superdiffusive\r\nvalue z = 3/2.

Here we offer a microscopic explanation of this effect, and we propose a closely related dc transport phenomenon—an off-diagonal symmetric conductivity, linear and odd in a magnetic field, which we refer to as linear magnetoconductivity (LMC). Although LMC has the same functional dependence on a magnetic field as the Hall effect, its origin is fundamentally different: LMC requires time-reversal symmetry to be broken even before a magnetic field is applied, and is therefore a sensitive probe of magnetism. We demonstrate LMC in three different ways: via a tight-binding toy model, a density functional theory calculation on MnPSe3, and a semiclassical treatment. The third approach identifies two distinct mechanisms yielding LMC: momentum-dependent band magnetization and Berry curvature. Finally, we propose an experimental geometry suitable for detecting LMC, and we demonstrate its applicability using Landauer-Büttiker simulations. Our results emphasize the importance of measuring the full conductivity tensor in magnetic materials, and they introduce LMC as a new transport probe of symmetry."}],"volume":112,"article_type":"original","day":"06","citation":{"apa":"Sunko, V., Liu, C., Vila, M., Na, I., Tang, Y., Kozii, V., … Orenstein, J.

Here, we report on a microscopic tight-binding model that unveils a unique coupling between orbitals and spins in 𝑑-wave altermagnets, which gives rise to momentum-dependent and spin-selective optical absorption. This coupling promotes the controlled optical excitation of up or down spins depending on the polarization direction of linearly polarized light. Such an effect originates from the coupling of orbitals to the sublattice degree of freedom through the crystal field, which is then coupled to spins through the antiferromagnetic interaction. Our crystal field analysis, which is general to any type of altermagnet, helps understand the onset of altermagnetism from a microscopic point of view, and we use our results to propose clear magneto-optical signatures of our predictions. Our findings shine light on the interplay between orbitals and spins in altermagnets, thus paving the way towards novel orbitronic and optospintronic devices.","lang":"eng"}],"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"citation":{"short":"M.

Using tensor-network simulations, we observe oscillatory behavior of local expectation values and bipartite entanglement entropy. We explain these oscillations deep in the many-body localized spin-glass regime via a simple theoretical model.

Proximity-induced superconducting correlations are an essential part of such devices. While the proximity effect in the conduction band of common semiconductors is well understood, its manifestation in confined hole gases, realized for instance in germanium, is an active area of research. Lower-dimensional hole-based systems, particularly in germanium, are emerging as an attractive platform for a variety of solid-state quantum devices, due to their combination of efficient spin and charge control and long coherence times. The recent experimental realization of the proximity effect in germanium thus calls for a theoretical description that is tailored to hole gases. In this work, we propose a simple model to describe proximity-induced superconductivity in two-dimensional hole gases, incorporating both the heavy-hole (HH) and light-hole (LH) bands. We start from the Luttinger–Kohn model, introduce three parameters that characterize hopping across the superconductor–semiconductor interface, and derive explicit intraband and interband effective pairing terms for the HH and LH bands. Unlike previous approaches, our theory provides a quantitative relationship between induced pairings and interface properties. Restricting our general model to an experimentally relevant case where only the HH band crosses the chemical potential, we predict the coexistence of 𝑠-wave and 𝑑-wave singlet pairings, along with triplet-type pairings, and modified Zeeman and Rashba spin–orbit couplings. Our results thus present a starting point for theoretical modeling of quantum devices based on proximitized hole gases, fueling further progress in quantum technology.","lang":"eng"}],"volume":111,"scopus_import":"1","day":"18","article_type":"original","project":[{"_id":"34a7f947-11ca-11ed-8bc3-c5dc2bbaae25","grant_number":"F8609","name":"Center for Correlated Quantum Materials and Solid State Quantum Systems: Probing topology in circuits and quantum materials"}],"date_created":"2025-06-19T16:54:54Z","external_id":{"arxiv":["2412.04084"],"isi":["001514328000004"]},"article_number":"214518","month":"06","OA_place":"publisher","article_processing_charge":"Yes (via OA deal)","department":[{"_id":"MaSe"},{"_id":"GradSch"}],"OA_type":"hybrid","publication_status":"published","fulldoi":"https://doi.org/10.1103/k4jh-pnxy","date_published":"2025-06-18T00:00:00Z","type":"journal_article","arxiv":1,"publisher":"American Physical Society","intvolume":" 111","author":[{"first_name":"Serafim","id":"e63d75c3-72ef-11ef-b75a-e303e149911f","full_name":"Babkin, Serafim","last_name":"Babkin"},{"last_name":"Joecker","full_name":"Joecker, Benjamin","first_name":"Benjamin"},{"first_name":"Karsten","last_name":"Flensberg","full_name":"Flensberg, Karsten"},{"id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","orcid":"0000-0002-2399-5827","last_name":"Serbyn","full_name":"Serbyn, Maksym"},{"full_name":"Danon, Jeroen","last_name":"Danon","first_name":"Jeroen"}],"oa":1,"corr_author":"1","date_updated":"2025-09-30T12:53:47Z","title":"Superconducting proximity effect in two-dimensional hole gases","year":"2025","doi":"10.1103/k4jh-pnxy","quality_controlled":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","has_accepted_license":"1","status":"public","isi":1,"_id":"19852"},{"publication_status":"published","OA_place":"publisher","article_processing_charge":"Yes (via OA deal)","month":"07","OA_type":"hybrid","department":[{"_id":"MaSe"}],"external_id":{"arxiv":["2404.11645"],"isi":["001530465500007"]},"article_number":"014301","date_created":"2025-09-10T05:44:47Z","arxiv":1,"related_material":{"record":[{"status":"public","id":"19791","relation":"research_data"}]},"date_published":"2025-07-01T00:00:00Z","type":"journal_article","fulldoi":"https://doi.org/10.1103/mfg2-t6gb","oa":1,"author":[{"last_name":"Desaules","full_name":"Desaules, Jean-Yves Marc","first_name":"Jean-Yves Marc","id":"6c292945-a610-11ed-9eec-c3be1ad62a80","orcid":"0000-0002-3749-6375"},{"first_name":"Thomas","full_name":"Iadecola, Thomas","last_name":"Iadecola"},{"first_name":"Jad C.","full_name":"Halimeh, Jad C.","last_name":"Halimeh"}],"corr_author":"1","publisher":"American Physical Society","intvolume":" 112","PlanS_conform":"1","_id":"20327","isi":1,"quality_controlled":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","has_accepted_license":"1","status":"public","title":"Mass-assisted local deconfinement in a confined Z2 lattice gauge theory","date_updated":"2025-09-30T14:34:43Z","year":"2025","doi":"10.1103/mfg2-t6gb","file_date_updated":"2025-09-10T06:47:23Z","file":[{"date_created":"2025-09-10T06:47:23Z","file_name":"2025_PhysReviewB_Desaules.pdf","checksum":"dd919bb9c4c233eba047af4262e02835","content_type":"application/pdf","date_updated":"2025-09-10T06:47:23Z","access_level":"open_access","success":1,"creator":"dernst","file_size":3458424,"relation":"main_file","file_id":"20333"}],"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"citation":{"apa":"Desaules, J.-Y.

As such, a theoretical understanding of the effect of confinement on LGT dynamics is not only of fundamental importance but also can lend itself to upcoming experiments. Here we show how confinement in a Z2 LGT can be avoided by proximity to a resonance between the fermion mass and the electric field strength. Furthermore, we show that this local deconfinement can become global for certain initial conditions, where information transport occurs over the entire chain. In addition, we show how this can lead to strong quantum many-body scarring starting in different initial states. Our findings provide deeper insights into the nature of confinement in Z2 LGTs and can be tested on current and near-term quantum devices.","lang":"eng"}],"volume":112},{"publication":"Physical Review B","volume":112,"abstract":[{"lang":"eng","text":"Cavity-magnon polaritons are hybrid excitations from the interaction between cavity photons and magnons, the quanta of collective spin oscillations. Along with the tunability of the magnon-photon coupling strength, fast information transfer and conversion speed are desired in hybrid devices. This can be achieved utilizing the propagating nature of spin waves with nonzero momentum for their ultrafast time dynamics and reduced ohmic dissipation. Antiferromagnets are particularly interesting as hosts for magnons since stray-field interactions are minimized and they support multiple modes with distinctive magnetic-field behavior across the phase diagram. Chromium trichloride (CrCl3) is a van der Waals layered antiferromagnet having a strong easy-plane anisotropy and a weak in-plane easy-axis anisotropy. Despite some magnetic resonance studies, the impact of magnetic reorientation of spins in CrCl3 on the cavity-magnon-polariton interaction strength as a function of magnetic field remains largely unexplored. In this study, we investigate the coupling between magnons in CrCl3 and photons in a coplanar waveguide resonator as a function of magnetic field. In particular, we find that the magnon-photon coupling strength varies nonmonotonically and distinctly with the magnetic field for the acoustic and the optical magnons, which can be utilized to tune the magnon-photon coupling strength using an external magnetic field as a knob. We find the signature of spin-flop transition in the two harmonics of the cavity due to a stronger dispersive coupling between optical magnons and cavity photons at lower fields. Additionally, we find standing modes formed by spin waves with nonzero momentum associated with the two hybrid magnons when the external field is applied at an angle with the crystal plane. These modes do not undergo substantial coupling with the cavity mode unlike the antiferromagnetic modes and can be used as low-loss propagation channels in hybrid devices."}],"day":"19","article_type":"original","scopus_import":"1","citation":{"ieee":"S.

Herein, we have performed a theoretical investigation on the anharmonic lattice dynamics and thermal property of perovskite Rb2SnBr6 and Cs2SnBr6 under strains using perturbation theory up to the fourth-order terms and the unified thermal transport theory. We demonstrate a pronounced hardening of low-frequency optical phonons as temperature increases, indicating strong lattice anharmonicity and the necessity of adopting temperature-dependent interatomic force constants in the lattice thermal conductivity (\r\nκL) calculations. It is found that the low-lying optical phonon modes of Rb2SnBr6 are extremely soft and their phonon energies are almost strain independent, which ultimately lead to a lower \r\nκL and a weaker strain dependence than Cs2SnBr6. We further reveal that the strain dependence of these phonon modes in the A2XB6-type perovskites weakens as their ibrational frequency decreases. This study deepens the understanding of lattice thermal transport in perovskites A2XB6 and provides a perspective on the selection of materials that meet the expected thermal behaviors in practical applications."}],"publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"citation":{"mla":"Cheng, Ruihuan, et al. “Impact of Strain-Insensitive Low-Frequency Phonon Modes on Lattice Thermal Transport in AxXB6-Type Perovskites.” Physical Review B, vol. 109, no. 5, 054305, American Physical Society, 2024, doi:10.1103/physrevb.109.054305.","ista":"Cheng R, Zeng Z, Wang C, Ouyang N, Chen Y. 2024.

This quantity, known as the magnetotropic susceptibility, 𝑘, relates to the second derivative of the free energy with respect to the angle of rotation. We have used approximation-free, auxiliary-field quantum Monte Carlo simulations for a realistic model of 𝛼−RuCl3 and optimized the path integral to alleviate the negative sign problem. This allows us to reach temperatures down to 30K—an energy scale below the dominant Kitaev coupling. We demonstrate that the magnetotropic spin susceptibility in this model of 𝛼−RuCl3 displays scaling behavior 𝑘=𝑇⁢𝑓⁡(𝐵/𝑇) at high temperatures. Once the uniform susceptibility departs from the Curie law (i.e., at the energy scale of the exchange interactions), it appears to transition to an emergent scalinglike behavior, characterized by a different function 𝑓 at lower temperatures, stemming from the locality of torque fluctuations. We observe a remarkable numerical match between experiment and simulations and we also find qualitative agreement with the pure Kitaev model. In comparison, for the XXZ Heisenberg Hamiltonian, the scaling 𝑘=𝑇⁢𝑓⁡(𝐵/𝑇) breaks down at a temperature scale where the uniform spin susceptibility deviates from the Curie law and never reemerges at low temperatures."}],"volume":110,"supplementarymaterial":"yes","scopus_import":"1","day":"15","article_type":"letter_note"},{"author":[{"full_name":"Franco, D.

At zero field, a second-order antiferromagnetic transition occurs at TN1≈1 K followed by a first-order transition at TN2≈0.45 K.

Through extensive numerical simulations we find that the domain wall state shows a variety of dynamical behaviors from localization all the way to ballistic transport, depending on the value of the reflection breaking parameter. Surprisingly, such anomalous behavior is not mirrored in infinite-temperature dynamics, which appear to scale diffusively, in line with expectations for generic interacting models. However, studying the particle density gradient, we show that the lack of reflection symmetry affects infinite-temperature dynamics, resulting in an asymmetric dynamical structure factor.

Our focus is on systems where isotropic or anisotropic impurity-boson interactions support a shallow bound state. To study the fate of the angulon in the vicinity of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian. First, we use it to study attractive, spherically symmetric impurity-boson interactions for which the linear rotor can be mapped onto a static impurity. The well-known polaron formalism provides an adequate description in this limit. Second, we consider anisotropic potentials, and show that the presence of a shallow bound state with pronounced anisotropic character leads to a many-body instability that washes out the angulon dynamics."}],"supplementarymaterial":"no","volume":109,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2308.03852"}],"publication_status":"published","month":"01","article_processing_charge":"No","OA_place":"repository","OA_type":"green","department":[{"_id":"MiLe"}],"external_id":{"isi":["001172754500002"],"arxiv":["2308.03852"]},"article_number":"014102","date_created":"2024-01-21T23:00:57Z","arxiv":1,"date_published":"2024-01-01T00:00:00Z","type":"journal_article","fulldoi":"https://doi.org/10.1103/PhysRevB.109.014102","das_tickbox":"0","author":[{"orcid":"0000-0003-2586-3702","first_name":"Tibor","id":"7e3293e2-b9dc-11ee-97a9-cd73400f6994","full_name":"Dome, Tibor","last_name":"Dome"},{"full_name":"Volosniev, Artem","last_name":"Volosniev","orcid":"0000-0003-0393-5525","first_name":"Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87"},{"id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","first_name":"Areg","orcid":"0000-0001-9666-3543","last_name":"Ghazaryan","full_name":"Ghazaryan, Areg"},{"last_name":"Safari","full_name":"Safari, Laleh","first_name":"Laleh","id":"3C325E5E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Richard","full_name":"Schmidt, Richard","last_name":"Schmidt"},{"first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6990-7802","last_name":"Lemeshko","full_name":"Lemeshko, Mikhail"}],"oa":1,"corr_author":"1","intvolume":" 109","publisher":"American Physical Society","_id":"14845","isi":1,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","quality_controlled":"1","status":"public","date_updated":"2026-10-16T12:16:12Z","title":"Linear rotor in an ideal Bose gas near the threshold for binding","year":"2024","doi":"10.1103/PhysRevB.109.014102"},{"corr_author":"1","author":[{"last_name":"Volosniev","full_name":"Volosniev, Artem","first_name":"Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0393-5525"},{"full_name":"Shiva Kumar, Abhishek","last_name":"Shiva Kumar","first_name":"Abhishek","id":"5e9a6931-eb97-11eb-a6c2-e96f7058d77a"},{"full_name":"Lorenc, Dusan","last_name":"Lorenc","id":"40D8A3E6-F248-11E8-B48F-1D18A9856A87","first_name":"Dusan"},{"id":"e32c111f-f6e0-11ea-865d-eb955baea334","first_name":"Younes","last_name":"Ashourishokri","full_name":"Ashourishokri, Younes"},{"last_name":"Zhumekenov","full_name":"Zhumekenov, Ayan","first_name":"Ayan"},{"last_name":"Bakr","full_name":"Bakr, Osman M.","first_name":"Osman M."},{"last_name":"Lemeshko","full_name":"Lemeshko, Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","orcid":"0000-0002-6990-7802"},{"id":"45E67A2A-F248-11E8-B48F-1D18A9856A87","first_name":"Zhanybek","orcid":"0000-0002-7183-5203","last_name":"Alpichshev","full_name":"Alpichshev, Zhanybek"}],"oa":1,"publisher":"American Physical Society","intvolume":" 107","_id":"12724","isi":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","quality_controlled":"1","status":"public","doi":"10.1103/physrevb.107.125201","title":"Effective model for studying optical properties of lead halide perovskites","date_updated":"2024-10-09T21:04:46Z","year":"2023","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2204.04022","open_access":"1"}],"publication_status":"published","department":[{"_id":"GradSch"},{"_id":"ZhAl"},{"_id":"MiLe"}],"article_processing_charge":"No","month":"03","article_number":"125201","external_id":{"isi":["000972602200006"],"arxiv":["2204.04022"]},"date_created":"2023-03-14T13:13:05Z","arxiv":1,"date_published":"2023-03-15T00:00:00Z","type":"journal_article","fulldoi":"https://doi.org/10.1103/physrevb.107.125201","publication":"Physical Review B","article_type":"original","day":"15","scopus_import":"1","volume":107,"abstract":[{"lang":"eng","text":"We use general symmetry-based arguments to construct an effective model suitable for studying optical properties of lead halide perovskites.

As a first application, we study two basic optical characteristics of the material: the Verdet constant and the refractive index. Beyond these linear characteristics of the material, the model is suitable for calculating nonlinear effects such as the third-order optical susceptibility. Analysis of this quantity shows that the geometrical properties of the spin-electric term imply isotropic optical response of the system, and that optical anisotropy of lead halide perovskites is a manifestation of hopping of charge carriers.

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."}],"day":"01","article_type":"original","scopus_import":"1","citation":{"apa":"Ghazaryan, A., Holder, T., Berg, E., & Serbyn, M.
