上一条：Energy eigenstates as pointer states in systems with weak coupling to environment:Proof is given for a generic coupling and a generic chaotic environment

下一条：Quantum Loschmidt echo or fidelity decay in classically chaotic and regular systems.Main achievements: a uniform semiclassical approach to fidelity decay in systems with weak chaos in the classical limit, a general semiclassical expression for fidelity decay in the Lyapunov regime of systems with chaotic classical limit, semiclassical expressions of fidelity decay in regular systems
