Quantum revivals and many-body localization
We show that the magnetization of a single “qubit” spin weakly coupled to an otherwise
isolated disordered spin chain exhibits periodic revivals in the localized regime, and retains …

Decay of spin-spin correlations in disordered quantum and classical spin chains
J Richter, D Schubert, R Steinigeweg - Physical Review Research, 2020 - APS
The real-time dynamics of equal-site correlation functions is studied for one-dimensional
spin models with quenched disorder. Focusing on infinite temperature, we present a …

Density dynamics in the mass-imbalanced Hubbard chain
We consider two mutually interacting fermionic particle species on a one-dimensional lattice
