A hybrid method for calculation of Ruelle-Pollicott resonances
Martin Horvat, Gregor Veble
We present a numerical method for calculation of Ruelle-Pollicott resonances of dynamical systems. It constructs an effective coarse-grained propagator by considering the correlati…
Expanded boundary integral method and chaotic time-reversal doublets in quantum billiards
Gregor Veble, Tomaz Prosen, Marko Robnik
We present the expanded boundary integral method for solving the planar Helmholtz problem, which combines the ideas of the boundary integral method and the scaling method and is ap…
Classical Loschmidt echo in chaotic many-body systems
Gregor Veble, Tomaz Prosen
General theoretic approach to classical Loschmidt echoes in chaotic systems with many degrees of freedom is developed. For perturbations which affect essentially all degrees of fre…
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…
On the stability of classical chaotic motion under system's perturbations
Giuliano Benenti, Giulio Casati, Gregor Veble
We study in detail the time behavior of classical fidelity for chaotic systems. We show in particular that the asymptotic decay, depending on system dynamical properties, can be ei…
Semiclassical analysis of Wigner functions
Gregor Veble, Marko Robnik, Valery Romanovski
In this work we study the Wigner functions, which are the quantum analogues of the classical phase space density, and show how a full rigorous semiclassical scheme for all orders o…
