Parametric correlations versus fidelity decay: the symmetry breaking case
H. Kohler, T. Nagao, H. -J. Stöckmann
We derive fidelity decay and parametric energy correlations for random matrix ensembles where time--reversal invariance of the original Hamiltonian is broken by the perturbation. L…

A random matrix theory of decoherence
T. Gorin, C. Pineda, H. Kohler +1
Random matrix theory is used to represent generic loss of coherence of a fixed central system coupled to a quantum-chaotic environment, represented by a random matrix ensemble, via…
