Induced Violation of Time-Reversal Invariance in the Regime of Weakly Overlapping Resonances
arXiv:0902.1418 · doi:10.1103/PhysRevLett.103.064101
Abstract
We measure the complex scattering amplitudes of a flat microwave cavity (a "chaotic billiard"). Time-reversal T-invariance is partially broken by a magnetized ferrite placed within the cavity. We extend the random-matrix approach to T-violation in scattering, fit some of the properties of the scattering amplitudes, and then successfully predict others. Our work constitutes the most precise test of the theoretical approach to T-violation within the framework of random-matrix theory so far available.
