Signatures of chaos and thermalization in the dynamics of many-body quantum systems.
We extend the results of two of our papers [Phys. Rev. A 94, 041603R (2016) and Phys. Rev. B 97, 060303R (2018)] that touch upon the intimately connected topics of quantum chaos and thermalization. In the first, we argued ...
Thouless and Relaxation Time Scales in Many-Body Quantum Systems.
Studies of the dynamics of isolated interacting many-body quantum systems are at the forefront of experimental and theoretical physics. A major open question is the identification of the time scales involved in the ...
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 ...
Dynamical signatures of quantum chaos and relaxation timescales in a spin-boson system.
(Philip Allan Publishers Limited, 2019-05-10)
Quantum systems whose classical counterparts are chaotic typically have highly correlated eigenvalues and level statistics that coincide with those from ensembles of full random matrices. A dynamical manifestation of these ...
