Decoherence,Orbit,and Classical Linear Frequency Entropy:Quantum-Classical Correspondence

The decoherence process is analyzed for an open quantum system that is classically chaotic,with a classicallinear frequency entropy developed to measure the stability of classical motion,Investigation shows that the decoherencemeasured by the rate of quantum linear entropy production varies significantly with both the underlying classical orbitsand the classical linear frequency entropy.Such correspondence is also supported by the further investigation on theLoschmidt Echo.
