Bringing such systems far from equilibrium, however, can drastically enhance mode-to-mode interactions. Understanding the resulting liquid is a fundamental question for quantum statistical mechanics and a practical question for engineering driven quantum devices. To tackle this question, we probe the non-equilibrium kinetics of one-dimensional plasmons in a long chain of Josephson junctions. We introduce multimode spectroscopy to controllably study the departure from equilibrium, witnessing the evolution from pairwise coupling between plasma modes at weak driving to dramatic, high-order, cascaded couplings at strong driving. Scaling to many-mode drives, we stimulate interactions between hundreds of modes, resulting in near-continuum internal dynamics. Imaging the resulting non-equilibrium plasmon populations, we then resolve the nonlocal redistribution of energy in the response to a weak perturbation—an explicit verification of the emergence of a strongly interacting, non-equilibrium liquid of plasmons."}],"DOAJ_listed":"1","citation":{"short":"A.

The protocol takes as input classical shadows corresponding to local randomized measurements, and outputs the tensors of an MPO maximizing a suitably defined fidelity with the experimental state. The tensor optimization is carried out sequentially, similarly to the well-known density matrix renormalization group algorithm. Our approach is provably efficient under certain technical conditions expected to be met in short-range correlated states and in typical noisy experimental settings. Under the same conditions, we also provide an efficient scheme to estimate fidelities between the learned and the experimental states. We experimentally demonstrate our protocol by learning entangled quantum states of up to N = 96 qubits in a superconducting quantum processor. Our method upgrades classical shadows to large-scale quantum computation and simulation experiments.","lang":"eng"}],"date_updated":"2026-03-23T15:39:34Z","year":"2026","article_processing_charge":"Yes (in subscription journal)","article_type":"original","author":[{"first_name":"Matteo","last_name":"Votto","full_name":"Votto, Matteo"},{"full_name":"Ljubotina, Marko","id":"F75EE9BE-5C90-11EA-905D-16643DDC885E","first_name":"Marko","last_name":"Ljubotina","orcid":"0000-0003-0038-7068"},{"full_name":"Lancien, Cécilia","first_name":"Cécilia","last_name":"Lancien"},{"last_name":"Cirac","first_name":"J.

Their quantum counterparts have recently drawn attention for exhibiting highly degenerate eigenstates at zero energy—known as zero modes—stemming from chiral symmetry. Yet, the structure and implications of these zero modes remain poorly understood. In this work, we focus on the properties of the zero mode subspace in quantum kinetically constrained models with a U(1) particle-conservation symmetry. We use the U(1) East, which lacks inversion symmetry, and the inversion-symmetric U(1) East-West models to illustrate our two main results. First, we observe that the simultaneous presence of constraints and chiral symmetry generally leads to a parametric increase in the number of zero modes due to the fragmentation of the many-body\r\nHilbert space into disconnected sectors. Second, we generalize the concept of compact localized states from single-particle physics and introduce the notion of collective bound states, a special kind of nonergodic eigenstates that are robust to enlarging the system size. We formulate sufficient criteria for their existence, arguing that the degenerate zero mode subspace plays a central role, and demonstrate bound states in both example models and in a two-dimensional model, the U(1) North-East, and in the pairflip model, a system without particle conservation. Our results motivate a systematic study of bound states and their relation to ergodicity breaking, transport, and other properties of quantum kinetically constrained\r\nmodels.

In this work, we characterize the dynamical properties of a disordered spin chain, focusing on the spin-glass regime. 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. From perturbation theory, we predict the timescales up to which our analytical description is valid and confirm it with numerical simulations. Finally, we study the correlation length dynamics, which, after a long-time plateau, resume growing in line with renormalization group (RG) expectations. Our work suggests that RG predictions can be quantitatively tested against numerical simulations and experiments, potentially enabling microscopic descriptions of dynamical phases in large systems.","lang":"eng"}],"type":"journal_article","article_number":"L220202","date_created":"2025-06-13T06:09:38Z","oa_version":"Published Version","oa":1,"isi":1,"issue":"22","scopus_import":"1","title":"Probing the many-body localized spin-glass phase through quench dynamics","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","year":"2025","article_processing_charge":"Yes (in subscription journal)","article_type":"letter_note","author":[{"full_name":"Brighi, Pietro","id":"4115AF5C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7969-2729","last_name":"Brighi","first_name":"Pietro"},{"full_name":"Ljubotina, Marko","id":"F75EE9BE-5C90-11EA-905D-16643DDC885E","first_name":"Marko","last_name":"Ljubotina","orcid":"0000-0003-0038-7068"},{"last_name":"Serbyn","orcid":"0000-0002-2399-5827","first_name":"Maksym","full_name":"Serbyn, Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87"}],"intvolume":" 111","month":"06","project":[{"_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","call_identifier":"H2020","name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control","grant_number":"850899"}],"OA_type":"hybrid","doi":"10.1103/9fms-ygfz","file_date_updated":"2025-06-23T06:28:17Z","OA_place":"publisher","ec_funded":1,"publisher":"American Physical Society","publication_status":"published","publication":"Physical Review B","volume":111,"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)"},"arxiv":1,"file":[{"relation":"main_file","date_created":"2025-06-23T06:28:17Z","file_id":"19861","creator":"dernst","date_updated":"2025-06-23T06:28:17Z","content_type":"application/pdf","checksum":"7941f92124793a383ca132eee2c289c5","file_size":1082749,"file_name":"2025_PhysReviewB_Brighi.pdf","access_level":"open_access","success":1}],"publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"day":"12","status":"public","external_id":{"arxiv":["2502.08192"],"isi":["001511503800006"]},"ddc":["530"],"acknowledgement":"We thank D.

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."}],"_id":"19852","date_updated":"2025-09-30T12:53:47Z","has_accepted_license":"1","language":[{"iso":"eng"}],"oa_version":"Published Version","date_created":"2025-06-19T16:54:54Z","type":"journal_article","article_number":"214518","issue":"21","oa":1,"isi":1,"publication":"Physical Review B","volume":111,"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)"},"publisher":"American Physical Society","publication_status":"published","day":"18","status":"public","file":[{"success":1,"file_name":"2025_PhysReviewB_Babkin.pdf","access_level":"open_access","file_size":1719489,"checksum":"fa8757f4780cfaeb51579c626284a8c1","content_type":"application/pdf","creator":"dernst","date_updated":"2025-06-23T10:31:11Z","file_id":"19869","relation":"main_file","date_created":"2025-06-23T10:31:11Z"}],"arxiv":1,"publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"quality_controlled":"1","ddc":["530"],"external_id":{"arxiv":["2412.04084"],"isi":["001514328000004"]},"acknowledgement":"We acknowledge useful discussions with Georgios Katsaros, Andrew Higginbotham, and Oliver Schwarze.

The time-dependent variational principle (TDVP) provides a powerful tool to tackle this task by projecting quantum evolution onto a classical dynamical system within a variational manifold. In classical systems, periodic orbits play a crucial role in understanding the structure of the phase space and the long-term behavior of the system. However, finding periodic orbits is generally difficult, and their existence and properties in generic TDVP dynamics over matrix product states have remained largely unexplored. In this work, we develop an algorithm to systematically identify and characterize periodic orbits in TDVP dynamics. Applying our method to the periodically kicked Ising model, we uncover both stable and unstable periodic orbits. We characterize the Kolmogorov-Arnold-Moser tori in the vicinity of stable periodic orbits and track the change of the periodic orbits as we modify the Hamiltonian parameters. We observe that periodic orbits exist at any value of the coupling constant of the kicked Ising model between prethermal and fully thermalizing regimes, but their relevance to quantum dynamics and imprint on quantum eigenstates diminishes as the system leaves the prethermal regime. Our results demonstrate that periodic orbits provide valuable insights into the TDVP approximation of quantum many-body evolution and establish a closer connection between quantum and classical chaos."}],"date_updated":"2025-12-01T15:30:19Z","has_accepted_license":"1","language":[{"iso":"eng"}],"year":"2025","article_processing_charge":"Yes","intvolume":" 6","author":[{"last_name":"Petrova","first_name":"Elena","full_name":"Petrova, Elena","id":"0ac84990-897b-11ed-a09c-f5abb56a4ede"},{"id":"F75EE9BE-5C90-11EA-905D-16643DDC885E","full_name":"Ljubotina, Marko","last_name":"Ljubotina","orcid":"0000-0003-0038-7068","first_name":"Marko"},{"orcid":"0000-0002-8490-9312","last_name":"Yalniz","first_name":"Gökhan","full_name":"Yalniz, Gökhan","id":"66E74FA2-D8BF-11E9-8249-8DE2E5697425"},{"full_name":"Serbyn, Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","orcid":"0000-0002-2399-5827","last_name":"Serbyn"}],"related_material":{"link":[{"relation":"press_release","url":"https://ist.ac.at/en/news/reaching-for-the-quantum-scars/"}]},"article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Finding periodic orbits in projected quantum many-body dynamics","scopus_import":"1","PlanS_conform":"1"},{"month":"10","OA_type":"gold","doi":"10.1103/crwj-x7j8","file_date_updated":"2025-12-01T08:00:19Z","OA_place":"publisher","publisher":"American Physical Society","publication_status":"published","publication":"Physical Review Research","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)"},"volume":7,"file":[{"access_level":"open_access","file_name":"2025_PhysReviewResearch_Brighi.pdf","success":1,"file_size":483879,"content_type":"application/pdf","checksum":"c4e582ab64ab9f8fface70bf2fd31882","creator":"dernst","date_updated":"2025-12-01T08:00:19Z","file_id":"20715","relation":"main_file","date_created":"2025-12-01T08:00:19Z"}],"arxiv":1,"publication_identifier":{"eissn":["2643-1564"]},"day":"01","status":"public","ddc":["530"],"external_id":{"arxiv":["2504.02460"]},"acknowledgement":"F.B. thanks Giuseppe de Tomasi and Oskar A.

In this work, we shift the focus to dynamical probes, specifically the steady-state spin current, to investigate transport properties in a disordered, non-Hermitian XXZ spin chain. Through exact diagonalization for small systems and tensor-network methods for larger chains, we demonstrate that the steady-state current remains finite and decays exponentially with disorder strength, showing no evidence of a transition up to disorder values far beyond the previously claimed critical point. Our results reveal a stark discrepancy between spectral indicators, which suggest localization, and transport behavior, which indicates delocalization. This highlights the importance of dynamical observables in characterizing NH MBL and suggests that traditional spectral measures may not fully capture the physics of non-Hermitian systems. Additionally, we observe a noncommutativity of limits in system size and time, further complicating the interpretation of finite-size studies. These findings challenge the existence of NH MBL in the studied model and underscore the need for alternative approaches to understanding localization in non-Hermitian settings."}],"date_updated":"2025-12-01T08:02:13Z","type":"journal_article","article_number":"L042014","oa_version":"Published Version","date_created":"2025-11-30T23:02:08Z","oa":1,"issue":"4","scopus_import":"1","PlanS_conform":"1","title":"Finite steady-state current defies non-Hermitian many-body localization","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2025","article_processing_charge":"Yes (via OA deal)","article_type":"original","intvolume":" 7","author":[{"full_name":"Brighi, Pietro","id":"4115AF5C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7969-2729","last_name":"Brighi","first_name":"Pietro"},{"last_name":"Ljubotina","orcid":"0000-0003-0038-7068","first_name":"Marko","full_name":"Ljubotina, Marko","id":"F75EE9BE-5C90-11EA-905D-16643DDC885E"},{"full_name":"Roccati, Federico","first_name":"Federico","last_name":"Roccati"},{"full_name":"Balducci, Federico","last_name":"Balducci","first_name":"Federico"}]},{"title":"Stirring the false vacuum via interacting quantized bubbles on a 5,564-qubit quantum annealer","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","PlanS_conform":"1","scopus_import":"1","year":"2025","article_processing_charge":"Yes (via OA deal)","author":[{"last_name":"Vodeb","first_name":"Jaka","full_name":"Vodeb, Jaka"},{"full_name":"Desaules, Jean-Yves Marc","id":"6c292945-a610-11ed-9eec-c3be1ad62a80","last_name":"Desaules","orcid":"0000-0002-3749-6375","first_name":"Jean-Yves Marc"},{"full_name":"Hallam, Andrew","first_name":"Andrew","last_name":"Hallam"},{"full_name":"Rava, Andrea","first_name":"Andrea","last_name":"Rava"},{"full_name":"Humar, Gregor","last_name":"Humar","first_name":"Gregor"},{"full_name":"Willsch, Dennis","last_name":"Willsch","first_name":"Dennis"},{"full_name":"Jin, Fengping","first_name":"Fengping","last_name":"Jin"},{"full_name":"Willsch, Madita","first_name":"Madita","last_name":"Willsch"},{"first_name":"Kristel","last_name":"Michielsen","full_name":"Michielsen, Kristel"},{"first_name":"Zlatko","last_name":"Papić","full_name":"Papić, Zlatko"}],"intvolume":" 21","article_type":"original","related_material":{"link":[{"url":"https://ista.ac.at/en/news/dancing-bubbles-model-a-cosmic-disaster/","description":"News on ISTA Website","relation":"press_release"}]},"citation":{"chicago":"Vodeb, Jaka, Jean-Yves Marc Desaules, Andrew Hallam, Andrea Rava, Gregor Humar, Dennis Willsch, Fengping Jin, Madita Willsch, Kristel Michielsen, and Zlatko Papić. “Stirring the False Vacuum via Interacting Quantized Bubbles on a 5,564-Qubit Quantum Annealer.” Nature Physics.

Here we observe quantized bubble formation in real time, a key feature of false vacuum decay dynamics, using a quantum annealer with 5,564 superconducting flux qubits. We develop an effective model that captures both initial bubble creation and subsequent interactions, and remains accurate under dissipation.

QMBSs are non-thermal highly excited eigenstates that coexist with typical eigenstates in the spectrum of many-body Hamiltonians, and have since been reported in multiple theoretical models, including the so-called PXP model, approximately realized by Rydberg simulators. At the same time, questions of how common QMBSs are and in what models they are physically realized remain open.

Often, this challenge is framed as a combinatorial optimization problem, for which a common strategy employs simulated annealing, a Monte Carlo (MC)-based algorithm that updates spins one at a time. Yet, these localized updates can cause the system to become trapped in local minima. Cluster algorithms (CAs) were developed to address this limitation and have demonstrated considerable success in studying ferromagnetic systems; however, they tend to encounter percolation issues when applied to generic spin glasses. In this work, we introduce a novel CA designed to tackle these challenges by leveraging precomputed two-point correlations, aiming solve combinatorial optimization problems in the form of Max-Cut more efficiently. In our approach, clusters are formed probabilistically based on these correlations. Various classical and quantum algorithms can be employed to generate correlations that embody information about the energy landscape of the problem. By utilizing this information, the algorithm aims to identify groups of spins whose simultaneous flipping induces large transitions in configuration space with high acceptance probability - even at low energy levels - thereby escaping local minima more effectively. Notably, clusters generated using correlations from the Quantum Approximate Optimization Algorithm exhibit high acceptance rates at low temperatures. These acceptance rates often increase with circuit depth, accelerating the algorithm and enabling more efficient exploration of the solution space."}],"date_published":"2025-09-01T00:00:00Z","citation":{"ieee":"P.

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. This is in disagreement with normal diffusion and suggests that the model may also exhibit anomalous dynamics at infinite temperature in the thermodynamic limit. Finally, we observe low-entangled eigenstates in the spectrum of the model, a telltale sign of quantum many-body scars."}],"date_published":"2024-09-11T00:00:00Z","department":[{"_id":"MaSe"}],"citation":{"mla":"Brighi, Pietro, and Marko Ljubotina. “Anomalous Transport in the Kinetically Constrained Quantum East-West Model.” Physical Review B, vol. 110, no. 10, L100304, American Physical Society, 2024, doi:10.1103/PhysRevB.110.L100304.","short":"P.

Remarkably, we find a universal drift velocity given by a simple formula, which, at zero average magnetization, depends only on the values of SU(2) Casimir invariants associated with local spins. In the integrable case, the drift velocity formula is confirmed analytically based on the exact solution of thermodynamic Bethe ansatz equations. Finally, by inspecting the large fluctuations of the time-integrated current between two halves of the system in stationary maximum-entropy states, we demonstrate violation of the Gallavotti-Cohen symmetry, implying that such states cannot be regarded as equilibrium ones. We show that the scaled cumulant generating function of the time-integrated current instead obeys a generalized fluctuation relation."}],"date_updated":"2025-09-08T09:55:09Z","department":[{"_id":"MaSe"}],"citation":{"ama":"Zadnik L, Ljubotina M, Krajnik Ž, Ilievski E, Prosen T.

Generally, preparing a target entangled state via unitary evolution with time-dependent couplings is a challenging task and very little is known about the existence of solutions and their properties. In this work we develop a constructive approach for preparing matrix product states (MPS) via continuous unitary evolution. We provide an explicit construction of the operator that exactly implements the evolution of a given MPS along a specified direction in its tangent space. This operator can be written as a sum of local terms of finite range, yet it is in general non-Hermitian. Relying on the explicit construction of the non-Hermitian generator of the dynamics, we demonstrate the existence of a Hermitian sequence of operators that implements the desired MPS evolution with an error that decreases exponentially with the operator range. The construction is benchmarked on an explicit periodic trajectory in a translationally invariant MPS manifold. We demonstrate that the Floquet unitary generating the dynamics over one period of the trajectory features an approximate MPS-like eigenstate embedded among a sea of thermalizing eigenstates. These results show that our construction is not only useful for state preparation and control of many-body systems, but also provides a generic route towards Floquet scars—periodically driven models with quasilocal generators of dynamics that have exact MPS eigenstates in their spectrum.","lang":"eng"}],"has_accepted_license":"1","language":[{"iso":"eng"}],"date_created":"2024-10-29T16:04:05Z","oa_version":"Published Version","type":"journal_article","article_number":"040311","issue":"4","oa":1,"isi":1},{"pmid":1,"day":"27","status":"public","publication_identifier":{"issn":["0028-0836"],"eissn":["1476-4687"]},"publication":"Nature","volume":635,"publisher":"Springer Nature","publication_status":"published","quality_controlled":"1","external_id":{"isi":["001367935000029"],"pmid":["39604614"]},"doi":"10.1038/d41586-024-03649-y","OA_type":"closed access","month":"11","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","title":"Quantum scars make their mark in graphene","scopus_import":"1","author":[{"full_name":"Abanin, Dmitry","first_name":"Dmitry","last_name":"Abanin"},{"orcid":"0000-0002-2399-5827","last_name":"Serbyn","first_name":"Maksym","full_name":"Serbyn, Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87"}],"intvolume":" 635","article_type":"letter_note","year":"2024","article_processing_charge":"No","department":[{"_id":"MaSe"}],"page":"825-826","date_published":"2024-11-27T00:00:00Z","citation":{"apa":"Abanin, D., & Serbyn, M.

Here we show that in kinetically constrained many-body systems, the skin effect can instead manifest as dynamical amplification within the Fock space, beyond the intuitively expected and previously studied particle localization and clustering. We exemplify this non-Hermitian Fock skin effect in an asymmetric version of the PXP model and show that it gives rise to ergodicity-breaking eigenstates—the non-Hermitian analogs of quantum many-body scars. A distinguishing feature of these non-Hermitian scars is their enhanced robustness against external disorders. We propose an experimental realization of the non-Hermitian scar enhancement in a tilted Bose-Hubbard optical lattice with laser-induced loss. Additionally, we implement digital simulations of such scar enhancement on the IBM quantum processor. Our results show that the Fock skin effect provides a powerful tool for creating robust nonergodic states in generic open quantum systems.","lang":"eng"}],"date_published":"2024-11-22T00:00:00Z","citation":{"mla":"Shen, Ruizhe, et al. “Enhanced Many-Body Quantum Scars from the Non-Hermitian Fock Skin Effect.” Physical Review Letters, vol. 133, no. 21, 216601, American Physical Society, 2024, doi:10.1103/PhysRevLett.133.216601.","short":"R.
