A random matrix formulation of fidelity decay
T. Gorin, T. Prosen, T. H. Seligman
We propose to study echo dynamics in a random matrix framework, where we assume that the perturbation is time independent, random and orthogonally invariant. This allows to use a b…
Faster than Lyapunov decays of classical Loshcmidt echo
Gregor Veble, Tomaz Prosen
We show that in the classical interaction picture the echo-dynamics, namely the composition of perturbed forward and unperturbed backward hamiltonian evolution, can be treated as a…
Fourier law in the alternate mass hard-core potential chain
Baowen Li, Giulio Casati, Jiao Wang +1
We study energy transport in a one-dimensional model of elastically colliding particles with alternate masses and . In order to prevent total momentum conservation we confin…
Quantum freeze of fidelity decay for a class of integrable dynamics
Tomaz Prosen, Marko Znidaric
We discuss quantum fidelity decay of classically regular dynamics, in particular for an important special case of a vanishing time averaged perturbation operator, i.e. vanishing ex…
Theory of quantum Loschmidt echoes
Tomaz Prosen, Thomas H. Seligman, Marko Znidaric
In this paper we review our recent work on the theoretical approach to quantum Loschmidt echoes, i.e. various properties of the so called echo dynamics -- the composition of forwar…
Estimating purity in terms of correlation functions
Tomaz Prosen, Thomas H. Seligman, Marko Znidaric
We prove a rigorous inequality estimating the purity of a reduced density matrix of a composite quantum system in terms of cross-correlation of the same state and an arbitrary prod…
