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…
Fidelity amplitude of the scattering matrix in microwave cavities
R. Schaefer, T. Gorin, T. H. Seligman +1
The concept of fidelity decay is discussed from the point of view of the scattering matrix, and the scattering fidelity is introduced as the parametric cross-correlation of a given…
Experimental verification of fidelity decay: From perturbative to Fermi Golden Rule regime
R. Schaefer, T. Gorin, T. H. Seligman +1
The scattering matrix was measured for a flat microwave cavity with classically chaotic dynamics. The system can be perturbed by small changes of the geometry. We define the "scatt…
Correlation functions of scattering matrix elements in microwave cavities with strong absorption
R. Schaefer, T. Gorin, T. H. Seligman +1
The scattering matrix was measured for microwave cavities with two antennas. It was analyzed in the regime of overlapping resonances. The theoretical description in terms of a stat…
