Dynamical Chaos In Quantum Systems

Autors:

Abstract: 

Complex dynamics of a quantum periodically driven square well is considered. It is shown that analysis of its ensemble average energy time series provides an identification of its dynamics to be either regular or chaotic. It has been found that enhancement of the driving force causes the energy spectrum to look like a spectrum of some random process, which may be identified as the signature of chaos in a quantum system. 

Key words: 
dynamical chaos
quantum chaos
quantum oscillator.
