Spontaneous Decoherence in Coupled Quantum Kicked Rotators
arXiv:chao-dyn/9711021
Abstract
Quantum mechanical behavior of coupled N-kicked rotators is studied. In the large N limit each rotator evolves under influence of the mean-field generated by surrounding rotators. It is found that the system spontaneously generates classical chaos in the large N limit when the system parameter exceeds a critical value. Numerical simulation of a quantum rotator coupled to a classical rotator supports this idea.
