A unified time scale for quantum chaotic regimes
Ignacio S. Gomez, Ernesto P. Borges
We present a generalised time scale for quantum chaos dynamics, motivated by nonextensive statistical mechanics. It recovers, as particular cases, the relaxation (Heisenberg) and t…
An upper bound for the KS-entropy in quantum mixing systems
Ignacio S. Gomez
We present an upper bound for the Kolmogorov-Sinai entropy of quantum systems having a mixing quantum phase space. The method for this estimation is based on the following ingredie…
An estimation of the logarithmic timescale in an ergodic dynamics
Ignacio S. Gomez
An estimation of the logarithmic timescale in quantum systems having an ergodic dynamics in the semiclassical limit of quasiclassical large parameters, is presented. The estimation…
Lyapunov exponents and Hamiltonian poles in a non Hermitian dynamics
Ignacio S. Gomez
By means of expressing volumes in phase space in terms of traces of quantum operators, a relationship between the Hamiltonian poles and the Lyapunov exponents in a non Hermitian qu…
