First Experimental Evidence for Chaos-Assisted Tunneling in a Microwave Annular Billiard
C. Dembowski, H. -D. Graef, A. Heine +3
We report on first experimental signatures for chaos-assisted tunneling in a two-dimensional annular billiard. Measurements of microwave spectra from a superconducting cavity with…
Anderson Localization in a String of Microwave Cavities
C. Dembowski, H. -D. Graef, R. Hofferbert +3
The field distributions and eigenfrequencies of a microwave resonator which is composed of 20 identical cells have been measured. With external screws the periodicity of the cavity…
Coupled Microwave Billiards as a Model for Symmetry Breaking
H. Alt, C. I. Barbosa, H. -D. Graef +5
Two superconducting microwave billiards have been electromagnetically coupled in a variable way. The spectrum of the entire system has been measured and the spectral statistics ana…
Correlation-Hole Method for Spectra of Superconducting Microwave Billiards
H. Alt, H. -D. Graef, R. Hofferbert +5
The spectral fluctuation properties of various two- and three-dimensional superconducting billiard systems are investigated by employing the correlation-hole method. It rests on th…
Wave Dynamical Chaos in Superconducting Microwave Cavities
H. Rehfeld, H. Alt, C. Dembowski +4
During the last few years we have studied the chaotic behavior of special Euclidian geometries, so-called billiards, from the quantum or in more general sense "wave dynamical" poin…
Studies of chaotic Dynamics in a Three-Dimensional Superconducting Microwave Billiard
H. Alt, H. -D. Graef, R. Hofferbert +5
We present first measurements on a superconducting three-dimensional, partly chaotic microwave billiard shaped like a small deformed cup. We analyze the statistical properties of t…
