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…
