Dissipation-Stabilized Quantum Revivals in a Non-Hermitian Lattice Gauge Theory
Yevgeny Bar Lev, Jad C. Halimeh, Achilleas Lazarides
With the advent of quantum simulation experiments of lattice gauge theories (LGTs), an open question is the effect of non-Hermiticity on their rich physics. The well-known PXP mode…
Heavy-Tailed Hall Conductivity Fluctuations in Quantum Hall Transitions
Emuna Rimon, Eytan Grosfeld, Yevgeny Bar Lev
We study the full distribution of the zero-temperature Hall conductivity in a lattice model of the IQHE using the Kubo formula across disorder realizations. Near the localization-d…
Stark-Many body localization in interacting infinite dimensional systems
Hristiana Atanasova, André Erpenbeck, Emanuel Gull +2
We study bulk particle transport in a Fermi-Hubbard model on an infinite-dimensional Bethe lattice, driven by a constant electric field. Previous numerical studies showed that one…
Dynamic scaling relation in quantum many-body systems
Devendra Singh Bhakuni, Yevgeny Bar Lev
In delocalized systems, particle number fluctuations, also known as quantum surface roughness, and the mean-square displacement exhibit a temporal power-law growth followed by a sa…
Temporal fluctuations of correlators in integrable and chaotic quantum systems
Talía L. M. Lezama, Yevgeny Bar Lev, Lea F. Santos
We provide bounds on temporal fluctuations around the infinite-time average of out-of-time-ordered and time-ordered correlators of many-body quantum systems without energy gap dege…
Chaos enhancement in large-spin chains
Yael Lebel, Lea F. Santos, Yevgeny Bar Lev
We study the chaotic properties of a large-spin XXZ chain with onsite disorder and a small number of excitations above the fully polarized state. We show that while the classical l…
Circular Rosenzweig-Porter random matrix ensemble
Wouter Buijsman, Yevgeny Bar Lev
The Rosenzweig-Porter random matrix ensemble serves as a qualitative phenomenological model for the level statistics and fractality of eigenstates across the many-body localization…
Transport in Stark Many Body Localized Systems
Guy Zisling, Dante M. Kennes, Yevgeny Bar Lev
Using numerically exact methods we study transport in an interacting spin chain which for sufficiently strong spatially constant electric field is expected to experience Stark many…
Logarithmic, noise-induced dynamics in the Anderson insulator
Talía L. M. Lezama, Yevgeny Bar Lev
We study the dynamical behavior of the Anderson insulator in the presence of a local noise. We show that the noise induces logarithmically slow energy and entanglement growth, unti…
Suppression of heating by long-range interactions in periodically driven spin chains
Devendra Singh Bhakuni, Lea F. Santos, Yevgeny Bar Lev
We propose a mechanism to suppress heating in periodically driven many-body quantum systems by employing sufficiently long-range interactions and experimentally relevant initial co…
How many particles make up a chaotic many-body quantum system?
Guy Zisling, Lea F. Santos, Yevgeny Bar Lev
We numerically investigate the minimum number of interacting particles, which is required for the onset of strong chaos in quantum systems on a one-dimensional lattice with short-r…
Is there slow particle transport in the MBL phase?
David J. Luitz, Yevgeny Bar Lev
We analyze the saturation value of the bipartite entanglement and number entropy starting from a random product state deep in the MBL phase. By studying the probability distributio…
Studying dynamics in two-dimensional quantum lattices using tree tensor network states
Benedikt Kloss, Yevgeny Bar Lev, David R. Reichman
We analyze and discuss convergence properties of a numerically exact algorithm tailored to study the dynamics of interacting two-dimensional lattice systems. The method is based on…
Multifractality and its role in anomalous transport in the disordered XXZ spin-chain
David J. Luitz, Ivan M. Khaymovich, Yevgeny Bar Lev
The disordered XXZ model is a prototype model of the many-body localization transition (MBL). Despite numerous studies of this model, the available numerical evidence of multifract…
Emergent locality in systems with power-law interactions
David J. Luitz, Yevgeny Bar Lev
Locality imposes stringent constraints on the spreading of information in nonrelativistic quantum systems, which is reminiscent of a "light-cone," a casual structure arising in the…
Anomalous thermalization and transport in disordered interacting Floquet systems
Sthitadhi Roy, Yevgeny Bar Lev, David J. Luitz
Local observables in generic periodically driven closed quantum systems are known to relax to values described by periodic infinite temperature ensembles. At the same time, ergodic…
Time-dependent variational principle in matrix-product state manifolds: pitfalls and potential
Benedikt Kloss, Yevgeny Bar Lev, David Reichman
We study the applicability of the time-dependent variational principle in matrix product state manifolds for the long time description of quantum interacting systems. By studying i…
(Quasi)Periodic revivals in periodically driven interacting quantum systems
David J. Luitz, Achilleas Lazarides, Yevgeny Bar Lev
Recently it has been shown that interparticle interactions\emph ongenerically\emph default destroy dynamical localization in periodically driven systems, resulting in diffusive tra…
Absence of dynamical localization in interacting driven systems
David J. Luitz, Yevgeny Bar Lev, Achilleas Lazarides
Using a numerically exact method we study the stability of dynamical localization to the addition of interactions in a periodically driven isolated quantum system which conserves o…
Information propagation in isolated quantum systems
David J. Luitz, Yevgeny Bar Lev
Entanglement growth and out-of-time-order correlators (OTOC) are used to assess the propagation of information in isolated quantum systems. In this work, using large scale exact ti…
The Ergodic Side of the Many-Body Localization Transition
David J. Luitz, Yevgeny Bar Lev
Recent studies point towards nontriviality of the ergodic phase in systems exhibiting many-body localization (MBL), which shows subexponential relaxation of local observables, subd…
Many-Body Localization in System with a Completely Delocalized Single-Particle Spectrum
Yevgeny Bar Lev, David R. Reichman, Yoav Sagi
Many-body localization (MBL) in a one-dimensional Fermi Hubbard model with random on-site interactions is studied. While for this model all single-particle states are trivially del…
