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.

This exponential complexity naïvely renders a complete state characterization, for instance via the complete set of bipartite Renyi entropies for all disjoint regions, a challenging task. Recently, a compact way of storing subregions' purities by encoding them as amplitudes of a fictitious quantum wave function, known as entanglement feature, was proposed. Notably, the entanglement feature can be a simple object even for highly entangled quantum states. However the complexity and practical usage of the entanglement feature for general quantum states has not been explored. In this work, we demonstrate that the entanglement feature can be efficiently learned using only a polynomial amount of samples in the number of degrees of freedom through the so-called tensor cross interpolation (TCI) algorithm, assuming it is expressible as a finite bond dimension MPS. We benchmark this learning process on Haar and random MPS states, confirming analytic expectations. Applying the TCI algorithm to quantum eigenstates of various one dimensional quantum systems, we identify cases where eigenstates have entanglement feature learnable with TCI. We conclude with possible applications of the learned entanglement feature, such as quantifying the distance between different entanglement patterns and finding the optimal one-dimensional ordering of physical indices in a given state, highlighting the potential utility of the proposed purity interpolation method.","lang":"eng"}],"article_type":"original","type":"journal_article","oa_version":"Published Version","project":[{"call_identifier":"H2020","name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control","_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","grant_number":"850899"}],"citation":{"apa":"Kolisnyk, D., Medina Ramos, R.

While the ETH apparently holds across a wide range of interacting quantum systems, in this work, we show that it may require generalization in the presence of thermal first-order phase transitions. We introduce a class of all-to-all spin models, featuring first-order thermal phase transitions that stem from two distinct local maxima of entropy (two mean-field solutions that we dub “branches”) that exchange dominance in the many-body density of states as the energy is varied. We argue that, for energies in the vicinity of the thermal phase transition, eigenstate expectation values do not need to converge to the same thermal value. The system has a regime with coexistence of two classes of eigenstates corresponding to the two branches with distinct expectation values at the same energy density and another regime with Schrödinger-cat-like eigenstates that are interbranch superpositions; these two regimes are separated by an eigenstate phase transition. We propose a more general form of the ETH , support our results by semiclassical calculations and an exact diagonalization study of a microscopic spin model, and argue that the structure of eigenstates in the vicinity of thermal first-order phase transitions can be experimentally probed via nonequilibrium dynamics.","lang":"eng"}],"DOAJ_listed":"1","citation":{"ama":"Serbyn M, Avdoshkin A, Diessel OK, Huse DA.

Here, we theoretically demonstrate the existence of solitonic excitations in high-energy states of Rydberg atom chains in the regime of strong nearest-neighbor Rydberg blockade. These localized wave packets propagate directionally atop a special class of reviving initial states related to quantum many-body scars and are capable of carrying energy. Exhibiting long coherence times, these states constitute a form of non-ergodic quantum dynamics and can be efficiently implemented on Rydberg atom simulators.

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 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."}],"_id":"23029","title":"Plasmon decay and nonequilibrium steady states in Josephson junction chains","date_created":"2026-10-02T08:33:31Z","author":[{"first_name":"Lucia","last_name":"Vigliotti","id":"539e1e1a-e604-11ee-a1df-f02b018e5c8c","full_name":"Vigliotti, Lucia"},{"first_name":"Andrew P","last_name":"Higginbotham","id":"4AD6785A-F248-11E8-B48F-1D18A9856A87","full_name":"Higginbotham, Andrew P","orcid":"0000-0003-2607-2363"},{"orcid":"0000-0002-2399-5827","full_name":"Serbyn, Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","first_name":"Maksym","last_name":"Serbyn"}],"status":"public","volume":114,"file":[{"file_name":"2026_PhysicalReviewB_Vigliotti.pdf","date_updated":"2026-10-07T09:39:01Z","content_type":"application/pdf","file_size":2531016,"file_id":"23069","access_level":"open_access","relation":"main_file","creator":"dernst","success":1,"date_created":"2026-10-07T09:39:01Z","checksum":"95db327e1005564d09334763789ad7ae"}],"doi":"10.1103/cw3m-thsw","researchdata_availability":"yes","article_number":"194501","external_id":{"arxiv":["2603.06371"]},"month":"10","department":[{"_id":"MaSe"},{"_id":"AnHi"}],"publisher":"American Physical Society","day":"01","dataavailabilitystatement":"The data and the source code that support the findings of this paper are openly available at: https://doi.org/10.5281/zenodo.19456426.","oa":1,"corr_author":"1","fulldoi":"https://doi.org/10.1103/cw3m-thsw","das_tickbox":"1","arxiv":1,"date_published":"2026-10-01T00:00:00Z","file_date_updated":"2026-10-07T09:39:01Z","has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","year":"2026","quality_controlled":"1","publication_status":"published","intvolume":" 114","tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"ddc":["530"]},{"dataavailabilitystatement":"There are no publicly available research\r\ndata or software supporting this manuscript.

In this work, we show that\r\nfinite-temperature energy transport in this model provides a window into the emergence of superdiffusion. At\r\nfinite temperature, the energy autocorrelation function exhibits a crossover from short-time coherent dynamics to\r\nlong-time hydrodynamics. The short-time behavior is dominated by a single magnon band and can be understood\r\nanalytically. In momentum space, this regime is characterized by spectral weight near q = π. 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. Finite-temperature energy transport therefore provides a bridge between microscopic magnon\r\nphysics and late-time superdiffusion in the PXP model.","lang":"eng"}],"title":"Finite-temperature crossover from coherent magnons to energy superdiffusion in the PXP model","_id":"23095","status":"public","date_created":"2026-10-11T22:02:06Z","author":[{"full_name":"Shengtao, Jiang","last_name":"Shengtao","first_name":"Jiang"},{"full_name":"Desaules, Jean-Yves Marc","orcid":"0000-0002-3749-6375","id":"6c292945-a610-11ed-9eec-c3be1ad62a80","first_name":"Jean-Yves Marc","last_name":"Desaules"},{"orcid":"0000-0003-0038-7068","full_name":"Ljubotina, Marko","id":"F75EE9BE-5C90-11EA-905D-16643DDC885E","first_name":"Marko","last_name":"Ljubotina"},{"full_name":"Scaffidi, Thomas","last_name":"Scaffidi","first_name":"Thomas"}],"date_updated":"2026-10-14T05:44:58Z","supplementarymaterial":"yes","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Shengtao, J., Desaules, J.-Y.

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."}],"oa_version":"Published Version","type":"journal_article","article_type":"original","citation":{"ieee":"A.

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.","lang":"eng"}],"type":"conference","oa_version":"Preprint","author":[{"full_name":"Eder, Peter J.","last_name":"Eder","first_name":"Peter J."},{"last_name":"Kerschbaumer","first_name":"Aron","id":"ade85a9c-3200-11ee-973b-91c1eb240410","orcid":"0009-0002-2370-8661","full_name":"Kerschbaumer, Aron"},{"full_name":"Finžgar, Jernej Rudi","last_name":"Finžgar","first_name":"Jernej Rudi"},{"id":"CE680B90-D85A-11E9-B684-C920E6697425","first_name":"Raimel A","last_name":"Medina Ramos","full_name":"Medina Ramos, Raimel A","orcid":"0000-0002-5383-2869"},{"last_name":"Schuetz","first_name":"Martin J.

The non-perturbative nature of false vacuum decay and the limited experimental access to this process make it challenging to study, leaving several open questions regarding how true vacuum bubbles form, move and interact. 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.

As such, a theoretical understanding of the effect of confinement on LGT dynamics is not only of fundamental importance, but can lend itself to upcoming experiments. Here, we show how confinement in a Z2 LGT can be locally 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."}],"title":"Research Data for \"Mass-Assisted Local Deconfinement in a Confined Z2 Lattice Gauge Theory\"","_id":"19791","date_created":"2025-06-04T14:30:22Z","status":"public","author":[{"orcid":"0000-0002-3749-6375","full_name":"Desaules, Jean-Yves Marc","first_name":"Jean-Yves Marc","last_name":"Desaules","id":"6c292945-a610-11ed-9eec-c3be1ad62a80"}],"date_updated":"2025-09-30T14:34:42Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","related_material":{"link":[{"url":"https://arxiv.org/abs/2404.11645","relation":"preprint"}],"record":[{"status":"public","id":"20327","relation":"used_in_publication"}]},"citation":{"ama":"Desaules J-YM.

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"}],"title":"Probing the many-body localized spin-glass phase through quench dynamics","_id":"19833","author":[{"orcid":"0000-0002-7969-2729","full_name":"Brighi, Pietro","last_name":"Brighi","first_name":"Pietro","id":"4115AF5C-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Ljubotina","first_name":"Marko","id":"F75EE9BE-5C90-11EA-905D-16643DDC885E","orcid":"0000-0003-0038-7068","full_name":"Ljubotina, Marko"},{"orcid":"0000-0002-2399-5827","full_name":"Serbyn, Maksym","first_name":"Maksym","last_name":"Serbyn","id":"47809E7E-F248-11E8-B48F-1D18A9856A87"}],"date_created":"2025-06-13T06:09:38Z","status":"public","date_updated":"2025-09-30T12:48:10Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"mla":"Brighi, Pietro, et al. “Probing the Many-Body Localized Spin-Glass Phase through Quench Dynamics.” Physical Review B, vol. 111, no. 22, L220202, American Physical Society, 2025, doi:10.1103/9fms-ygfz.","ama":"Brighi P, Ljubotina M, Serbyn M.

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"}],"citation":{"chicago":"Babkin, Serafim, Benjamin Joecker, Karsten Flensberg, Maksym Serbyn, and Jeroen Danon. “Superconducting Proximity Effect in Two-Dimensional Hole Gases.” Physical Review B.

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"}],"title":"Mass-assisted local deconfinement in a confined Z2 lattice gauge theory","_id":"20327","date_created":"2025-09-10T05:44:47Z","author":[{"last_name":"Desaules","first_name":"Jean-Yves Marc","id":"6c292945-a610-11ed-9eec-c3be1ad62a80","full_name":"Desaules, Jean-Yves Marc","orcid":"0000-0002-3749-6375"},{"last_name":"Iadecola","first_name":"Thomas","full_name":"Iadecola, Thomas"},{"full_name":"Halimeh, Jad C.","first_name":"Jad C.","last_name":"Halimeh"}],"status":"public","date_updated":"2025-09-30T14:34:43Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","PlanS_conform":"1","related_material":{"record":[{"id":"19791","relation":"research_data","status":"public"}]},"citation":{"chicago":"Desaules, Jean-Yves Marc, Thomas Iadecola, and Jad C.

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.","lang":"eng"}],"article_number":"040333","isi":1,"volume":6,"file":[{"file_id":"20647","file_size":2504713,"file_name":"tldp-kvkd.pdf","date_updated":"2025-11-14T09:44:10Z","content_type":"application/pdf","checksum":"5d6d04ac518b4118405334e1ddc7a56d","date_created":"2025-11-14T09:44:10Z","success":1,"creator":"gyalniz","relation":"main_file","access_level":"open_access"}],"doi":"10.1103/tldp-kvkd","day":"12","oa":1,"corr_author":"1","external_id":{"arxiv":["2504.12472"],"isi":["001616473700003"]},"department":[{"_id":"GradSch"},{"_id":"BjHo"},{"_id":"MaSe"}],"month":"11","publisher":"American Physical Society","date_published":"2025-11-12T00:00:00Z","file_date_updated":"2025-11-14T09:44:10Z","has_accepted_license":"1","article_processing_charge":"Yes","fulldoi":"https://doi.org/10.1103/tldp-kvkd","arxiv":1,"APC_amount":"3599,50 EUR","ddc":["539"],"tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"year":"2025","quality_controlled":"1","publication_status":"published","intvolume":" 6"}]
