Long-range correlations in rectangular cavities containing pointlike perturbations
Long-range correlations in rectangular cavities containing pointlike perturbations
We investigated experimentally the short- and long-range correlations in the fluctuations of the resonance frequencies of flat, rectangular microwave cavities that contained antennas acting as pointlike perturbations. We demonstrate that their spectral properties exhibit the features typical for singular statistics. Hitherto, only the nearest-neighbor spacing distribution had been studied. In …
