Parametric correlations versus fidelity decay: the symmetry breaking
case    [PDF]

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. Like in the case of a symmetry conserving perturbation a simple relation between both quantities can be established.
