Nonperiodic echoes from mushroom billiard hats
B. Dietz, T. Friedrich, M. Miski-Oglu +3
Mushroom billiards have the remarkable property to show one or more clear cut integrable islands in one or several chaotic seas, without any fractal boundaries. The islands corresp…
An efficient method for scattering problems in open billiards: Theory and applications
Gursoy B. Akguc, Thomas H. Seligman
We present an efficient method to solve scattering problems in two-dimensional open billiards with two leads and a complicated scattering region. The basic idea is to transform the…
Dynamics of Loschmidt echoes and fidelity decay
Thomas Gorin, Tomaz Prosen, Thomas H. Seligman +1
Fidelity serves as a benchmark for the relieability in quantum information processes, and has recently atracted much interest as a measure of the susceptibility of dynamics to pert…
A Bell pair in a generic random matrix environment
Carlos Pineda, Thomas H. Seligman
Two non-interacting qubits are coupled to an environment. Both coupling and environment are represented by random matrix ensembles. The initial state of the pair is a Bell state, t…
First verification of generic fidelity recovery in a dynamical system
Carlos Pineda, Rudi Schaefer, Tomaz Prosen +1
We study the time evolution of fidelity in a dynamical many body system, namely a kicked Ising model, modified to allow for a time reversal invariance breaking. We find good agreem…
Anomalous slow fidelity decay for symmetry breaking perturbations
T. Gorin, H. Kohler, T. Prosen +3
Symmetries as well as other special conditions can cause anomalous slowing down of fidelity decay. These situations will be characterized, and a family of random matrix models to e…
