Crossover Driven by Time-Reversal Symmetry Breaking in Quantum Chaos
Crossover Driven by Time-Reversal Symmetry Breaking in Quantum Chaos
Parametric correlations of the energy spectra of quantum chaotic systems are presented in the presence of time-reversal symmetry-breaking perturbations. The spectra disperse as a function of two external perturbations, one of which preserves time-reversal symmetry, while the other violates it. Exact analytical expressions for the parametric two-point autocorrelation function of …
