上一条：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

下一条：Universal statistics for ratios of components of energy eigenfunctions in disordered and classically chaotic systems. Manifestations of the destruction of integrability, in particular in the neighborhood of avoided level crossings
