The many-body localization transition for a Heisenberg spin chain with a speckle disorder is studied. Such a model is equivalent to a system of spinless fermions in an optical lattice with an additional speckle field. Our numerical results show that the many-body localization transition in speckle disorder falls within the same universality class as the transition in an uncorrelated random disorder, in contrast to the quasiperiodic potential typically studied in experiments. This hints at… 
Ergodicity breaking with long-range cavity-induced quasiperiodic interactions
Many-body localization (MBL) behavior is analyzed in an extended Bose-Hubbard model with quasiperiodic infinite-range interactions. No additional disorder is present. Examining level statistics and

The transition of lateral spreading to localization in 3D disordered medium
Abstract In this paper, we mainly focus on the localization behavior in a three-dimensional disordered medium, which is designed by mixing controllable amounts of random particles to the homogenous


Many-body localization of bosons in an optical lattice: Dynamics in disorder-free potentials
The phenomenon of Many-Body Stark Localization of bosons in tilted optical lattice is studied. Despite the fact that no disorder is necessary for Stark localization to occur, it is very similar to
Lattice Gauge Theories and String Dynamics in Rydberg Atom Quantum Simulators
Gauge theories are the cornerstone of our understanding of fundamental interactions among particles. Their properties are often probed in dynamical experiments, such as those performed at ion
Many-body localization transition in large quantum spin chains: The mobility edge
Thermalization of random-field Heisenberg spin chain is probed by time evolution of density correlation functions. Studying the impacts of average energies of initial product states on dynamics of
Local constraints can globally shatter Hilbert space: a new route to quantum information protection
We show how local constraints can globally ‘shatter’ Hilbert space into subsectors, leading to an unexpected dynamics with features reminiscent of both many body localization and quantum scars. A
