Spectral properties of Dirac billiards at the van Hove singularities
B. Dietz, T. Klaus, M. Miski-Oglu +3
We study distributions of the ratios of level spacings of a rectangular and an Africa-shaped superconducting microwave resonator containing circular scatterers on a triangular grid…
Quantum and Wave Dynamical Chaos in Superconducting Microwave Billiards
B. Dietz, A. Richter
Experiments with superconducting microwave cavities have been performed in our laboratory for more than two decades. The purpose of the present article is to recapitulate some of t…
Spectral Properties and Dynamical Tunneling in Constant-Width Billiards
B. Dietz, T. Guhr, B. Gutkin +2
We determine with unprecedented accuracy the lowest 900 eigenvalues of two quantum constant-width billiards from resonance spectra measured with flat, superconducting microwave res…
Scattering Experiments with Microwave Billiards at an Exceptional Point under Broken Time Reversal Invariance
S. Bittner, B. Dietz, H. L. Harney +3
Scattering experiments with microwave cavities were performed and the effects of broken time-reversal invariance (TRI), induced by means of a magnetized ferrite placed inside the c…
Exceptional Points in a Microwave Billiard with Time-Reversal Invariance Violation
B. Dietz, H. L. Harney, O. N. Kirillov +3
We report on the experimental study of an exceptional point (EP) in a dissipative microwave billiard with induced time-reversal invariance (T) violation. The associated two-state H…
Experimental test of a trace formula for two-dimensional dielectric resonators
S. Bittner, E. Bogomolny, B. Dietz +4
Resonance spectra of two-dimensional dielectric microwave resonators of circular and square shapes have been measured. The deduced length spectra of periodic orbits were analyzed a…
