Experimental results on open microwave billiards — Stefan Bittner, Barbara Dietz-Pilatus, Thomas Friedrich, Maksim Miski-Oglu, •Pedro Oria-Iriarte, Achim Richter, and Florian Schäfer — Institut für Kernphysik, Schlossgartenstrasse 9, 64289 Darmstadt

Scattering properties, time evolution and diffraction patterns are investigated in different open microwave billiards. In an open circular billiard with an attached waveguide the survival probability is computed by means of a method proposed by Hannay, Dittes and Müller. Also the famous single and double slit experiments are performed in a microwave billiard on the basis of future experiments with regular and chaotic dynamics. In another experiment presented we test the random matrix description of spectral fluctuations and show that this analysis serves as a tool to learn about the dynamics of a system in the regime of overlapping resonances. Finally, we report on the decay for short times of open mushroom billiards, which we investigated for both the classical and quantum.
