Köber, Bernd and Kuhl, Ulrich and Stöckmann, Hans-Jürgen and Goussev, Arseni and Richter, Klaus (2011) Fidelity decay for local perturbations: microwave evidence for oscillating decay exponents. Phys Rev E 83, 016214.
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 from the Fermi Golden Rule to the escape-rate regime of the Loschmidt echo decay with increasing local boundary perturbation. In particular, we observe pronounced oscillations of the decay rate as a function of the piston ...
