Dynamics at the many-body localization transition.
(American Physical Society, 2015-07)
The isolated one-dimensional Heisenberg model with static random magnetic fields has become paradigmatic for the analysis of many-body localization. Here, we study the dynamics of this system initially prepared in a ...
Analytical description of the survival probability of coherent states in regular regimes.
(American Physical Society, 2018)
Using coherent states as initial states, we investigate the quantum dynamics of the Lipkin–Meshkov–Glick (LMG) and Dicke models in the semi-classical limit. They are representative models of bounded systems with one- and ...
Generic dynamical features of quenched interacting quantum systems: Survival probability, density imbalance, and out-of-time-ordered correlator.
(American Physical Society, 2018-02-23)
We study numerically and analytically the quench dynamics of isolated many-body quantum systems. Using full random matrices from the Gaussian orthogonal ensemble, we obtain analytical expressions for the evolution of the ...
