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…
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…
