Dynamics and transport at the threshold of many-body localization
S Gopalakrishnan, SA Parameswaran - Physics Reports, 2020 - Elsevier
Many-body localization (MBL) describes a class of systems that do not approach thermal
equilibrium under their intrinsic dynamics; MBL and conventional thermalizing systems form …

Avalanches and many-body resonances in many-body localized systems
We numerically study both the avalanche instability and many-body resonances in strongly
disordered spin chains exhibiting many-body localization (MBL). Finite-size systems behave …

Challenges to observation of many-body localization
P Sierant, J Zakrzewski - Physical Review B, 2022 - APS
We study time dynamics of 1D disordered Heisenberg spin-1/2 chains focusing on a regime
of large system sizes and a long-time evolution. This regime is relevant for observation of …

Quantum chaos challenges many-body localization
Characterizing states of matter through the lens of their ergodic properties is a fascinating
new direction of research. In the quantum realm, the many-body localization (MBL) was …

Distinguishing localization from chaos: Challenges in finite-size systems
We re-examine attempts to study the many-body localization transition using measures that
are physically natural on the ergodic/quantum chaotic regime of the phase diagram. Using …

Multifractal scalings across the many-body localization transition
In contrast with Anderson localization where a genuine localization is observed in real
space, the many-body localization (MBL) problem is much less understood in Hilbert space …

Realization of a discrete time crystal on 57 qubits of a quantum computer
Unconventional dynamical phases that violate ergodicity have been a subject of extensive
research in recent years. A periodically driven system is naively expected to lose all memory …

Ergodicity breaking transition in finite disordered spin chains
We study disorder-induced ergodicity breaking transition in high-energy eigenstates of
interacting spin-1/2 chains. Using exact diagonalization, we introduce a cost function …

Resonance-induced growth of number entropy in strongly disordered systems
R Ghosh, M Žnidarič - Physical Review B, 2022 - APS
We study the growth of the number entropy SN in one-dimensional number-conserving
interacting systems with strong disorder, which are believed to display many-body …
