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…
Experimental vs. Numerical Eigenvalues of a Bunimovich Stadium Billiard -- A Comparison
H. Alt, C. Dembowski, H. -D. Graef +4
We compare the statistical properties of eigenvalue sequences for a gamma=1 Bunimovich stadium billiard. The eigenvalues have been obtained by two ways: one set results from a meas…
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…
Mode Fluctuation Distribution for Spectra of Superconducting Microwave Billiards
H. Alt, C. Dembowski, H. -D. Graef +4
High resolution eigenvalue spectra of several two- and three-dimensional superconducting microwave cavities have been measured in the frequency range below 20 GHz and analyzed usin…
Wave Dynamical Chaos in a Superconducting Three-Dimensional Sinai Billiard
H. Alt, C. Dembowski, H. -D. Graef +5
Based on very accurate measurements performed on a superconducting microwave resonator shaped like a desymmetrized three-dimensional (3D) Sinai billiard, we investigate for the fir…
