Emergent anomalous hydrodynamics at infinite temperature in a long-range XXZ model

A Yang, JL Ma, L Ying - Physical Review B, 2024 - APS
The conventional wisdom suggests that transports of conserved quantities in nonintegrable
quantum many-body systems at high temperatures are diffusive. Recent study suggests a …

[HTML][HTML] Discrete time crystal phase of higher dimensional integrable models

R Chandra, A Roy - Physics Letters A, 2024 - Elsevier

Key observable for linear thermalization

Y Chiba, A Shimizu - Physical Review Research, 2023 - APS
For studies on thermalization of an isolated quantum many-body system, the fundamental
issue is to determine whether a given system thermalizes or not. However, most studies …

Prethermalization in the PXP Model under Continuous Quasiperiodic Driving
