Semiclassical Mechanism for the Quantum Decay in Open Chaotic Systems
Daniel Waltner, Martha Gutierrez, Arseni Goussev +1
We address the decay in open chaotic quantum systems and calculate semiclassical corrections to the classical exponential decay. We confirm random matrix predictions and, going bey…

Loschmidt echo for local perturbations: non-monotonous cross-over from the Fermi-golden-rule to the escape-rate regime
Arseni Goussev, Daniel Waltner, Klaus Richter +1
We address the sensitivity of quantum mechanical time evolution by considering the time decay of the Loschmidt echo (LE) (or fidelity) for local perturbations of the Hamiltonian. W…
