Quantum Fingerprints of Classical Ruelle-Pollicott Resonances
Quantum Fingerprints of Classical Ruelle-Pollicott Resonances
Quantum and classical correlations are studied experimentally in model n-disk microwave billiards. The wave vector kappa autocorrelation C(kappa) of the quantum spectrum displays nonuniversal oscillations for large kappa, comparable to the universal random matrix theory behavior observed for small kappa. The nonuniversal behavior is shown to be completely determined by …
