Dynamics of Loschmidt echoes and fidelity decay
Fidelity serves as a benchmark for the reliability in quantum information processes, and has
recently attracted much interest as a measure of the susceptibility of dynamics to …

Many-body localization in periodically driven systems
We consider disordered many-body systems with periodic time-dependent Hamiltonians in
one spatial dimension. By studying the properties of the Floquet eigenstates, we identify two …

Lyapunov exponent and out-of-time-ordered correlator's growth rate in a chaotic system
It was proposed recently that the out-of-time-ordered four-point correlator (OTOC) may serve
as a useful characteristic of quantum-chaotic behavior, because, in the semiclassical limit …

Periodically driven ergodic and many-body localized quantum systems
We study dynamics of isolated quantum many-body systems whose Hamiltonian is switched

Coherent destruction of tunneling
The phenomenon of tunneling is investigated for a symmetric double-well potential
perturbed by a monochromatic driving force. The analysis is based on a numerical treatment …

Chaos and the quantum phase transition in the Dicke model
C Emary, T Brandes - Physical Review E, 2003 - APS
We investigate the quantum-chaotic properties of the Dicke Hamiltonian; a quantum-optical
model that describes a single-mode bosonic field interacting with an ensemble of N two …

Quantum chaos triggered by precursors of a quantum phase transition: the Dicke model
C Emary, T Brandes - Physical review letters, 2003 - APS
We consider the Dicke Hamiltonian, a simple quantum-optical model which exhibits a zero-
temperature quantum phase transition. We present numerical results demonstrating that at …
