Friedel Oscillations in Microwave Billiards
A. Baecker, B. Dietz, T. Friedrich +4
Friedel oscillations of electron densities near step edges have an analog in microwave billiards. A random plane wave model, normally only appropriate for the eigenfunctions of a p…
Quantum Chaotic Scattering in Microwave Resonators
B. Dietz, T. Friedrich, H. L. Harney +4
In a frequency range where a microwave resonator simulates a chaotic quantum billiard, we have measured moduli and phases of reflection and transmission amplitudes in the regimes o…
Nonperiodic echoes from quantum mushroom billiard hats
B. Dietz, T. Friedrich, M. Miski-Oglu +3
Nonperiodic tunable quantum echoes have been observed in experiments with an open microwave billiard whose geometry under certain conditions provides Fibonacci like sequences of cl…
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…
Prevalence of marginally unstable periodic orbits in chaotic billiards
E. G. Altmann, T. Friedrich, A. E. Motter +2
The dynamics of chaotic billiards is significantly influenced by coexisting regions of regular motion. Here we investigate the prevalence of a different fundamental structure, whic…
Rabi Oscillations at Exceptional Points in Microwave Billiards
B. Dietz, T. Friedrich, J. Metz +4
We experimentally investigated the decay behavior with time t of resonances near and at exceptional points, where two complex eigenvalues and also the associated eigenfunctions coa…
