Second order quantum decoherence in the boson system
D. L. Zhou, C. P. Sun
Abstract
The second order quantum decoherence (SOQDC)is proposed as a novel description for the loss of quantum coherence only reflected by second order quantum correlations. By calculating the two-time correlation function, the phenomenon of SOQDC is studied in details for a simple model, a two boson system interacting with a reservoir composed of one or many bosons. The second order quantum decoherence effects can be observed in the sketched cavity QED experiment.
