Loschmidt Echo
Arseni Goussev, Rodolfo A. Jalabert, Horacio M. Pastawski +1
In this article we review the past, present, and future of the Loschmidt Echo.
Fidelity decay for local perturbations: microwave evidence for oscillating decay exponents
Bernd Köber, Ulrich Kuhl, Hans-Jürgen Stöckmann +2
We study fidelity decay in classically chaotic microwave billiards for a local, piston-like boundary perturbation. We experimentally verify a predicted non-monotonic cross-over fro…
A periodic orbit formula for quantum reactions through transition states
Roman Schubert, Holger Waalkens, Arseni Goussev +1
Transition State Theory forms the basis of computing reaction rates in chemical and other systems. Recently it has been shown how transition state theory can rigorously be realized…
Long-time saturation of the Loschmidt echo in quantum chaotic billiards
Martha Gutiérrez, Arseni Goussev
The Loschmidt echo (LE) (or fidelity) quantifies the sensitivity of the time evolution of a quantum system with respect to a perturbation of the Hamiltonian. In a typical chaotic s…
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…
Loschmidt echo decay from local boundary perturbations
Arseni Goussev, Klaus Richter
We investigate the sensitivity of the time evolution of semiclassical wave packets in two-dimensional chaotic billiards with respect to local perturbations of their boundaries. For…
