Comment on "Exploring chaos in the Dicke model using ground-state fidelity and the Loschmidt echo"
I. García-Mata, A. J. Roncaglia, D. A. Wisniacki
In [PRE \textbf{90}, 022920 (2014), arXiv:1404.6738] a study of the ground state fidelity of the Dicke model as a function of the coupling parameter is presented. Abrupt jumps of t…
Relaxation of isolated quantum systems beyond chaos
Ignacio García-Mata, Augusto J. Roncaglia, Diego A. Wisniacki
In classical statistical mechanics there is a clear correlation between relaxation to equilibrium and chaos. In contrast, for isolated quantum systems this relation is -- to say th…
Maximum population transfer in a periodically driven two-level system
P. M. Poggi, F. J. Arranz, R. M. Benito +2
We study the dynamics of a two-level quantum system under the influence of sinusoidal driving in the intermediate frequency regime. Analyzing the Floquet quasienergy spectrum, we f…
Universal wave functions structure in mixed systems
Diego A. Wisniacki
When a regular classical system is perturbed, non-linear resonances appear as prescribed by the KAM and Poincarè-Birkhoff theorems. Manifestations of this classical phenomena to th…
