Closed and open superconducting microwave waveguide networks as a model for quantum graphs
Barbara Dietz, Tobias Klaus, Marco Masi +4
We report on high-precision measurements that were performed with superconducting waveguide networks with the geometry of a tetrahedral and a honeycomb graph. They consist of junct…
Properties of the eigenmodes and quantum-chaotic scattering in a superconducting microwave Dirac billiard with threefold rotational symmetry
Weihua Zhang, Xiaodong Zhang, Jiongning Che +2
We report on experimental studies that were performed with a microwave Dirac billiard (DB), that is, a flat resonator containing metallic cylinders arranged on a triangular grid, w…
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…
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…
Experimental Test of a Two-dimensional Approximation for Dielectric Microcavities
S. Bittner, B. Dietz, M. Miski-Oglu +3
Open dielectric resonators of different shapes are widely used for the manufacture of microlasers. A precise determination of their resonance frequencies and widths is crucial for…
Induced Violation of Time-Reversal Invariance in the Regime of Weakly Overlapping Resonances
B. Dietz, T. Friedrich, H. L. Harney +5
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…
