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…
Dielectric Square Resonator Investigated with Microwave Experiments
S. Bittner, E. Bogomolny, B. Dietz +2
We present a detailed experimental study of the symmetry properties and the momentum space representation of the field distributions of a dielectric square resonator as well as the…
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…
Experimental Observation of Localized Modes in a Dielectric Square Resonator
S. Bittner, E. Bogomolny, B. Dietz +2
We investigated the frequency spectra and field distributions of a dielectric square resonator in a microwave experiment. Since such systems cannot be treated analytically, the exp…
Bound States in Sharply Bent Waveguides: Analytical and Experimental Approach
S. Bittner, B. Dietz, M. Miski-Oglu +4
Quantum wires and electromagnetic waveguides possess common features since their physics is described by the same wave equation. We exploit this analogy to investigate experimental…
Trace formula for chaotic dielectric resonators tested with microwave experiments
S. Bittner, B. Dietz, R. Dubertrand +3
We measured the resonance spectra of two stadium-shaped dielectric microwave resonators and tested a semiclassical trace formula for chaotic dielectric resonators proposed by Bogom…
