Spectral properties of microwave graphs with local absorption
M. Allgaier, S. Gehler, S. Barkhofen +2
The influence of absorption on the spectra of microwave graphs has been studied experimentally. The microwave networks were made up of coaxial cables and T junctions. First, absorp…
Universal Quantum Localizing Transition of a Partial Barrier in a Chaotic Sea
Matthias Michler, Arnd Bäcker, Roland Ketzmerick +2
Generic 2D Hamiltonian systems possess partial barriers in their chaotic phase space that restrict classical transport. Quantum mechanically the transport is suppressed if Planck's…
Fidelity decay for local perturbations: microwave evidence for oscillating decay exponents
Bernd Köber, Ulrich Kuhl, Hans-Jürgen Stöckmann +2
We study fidelity decay in classically chaotic microwave billiards for a local, piston-like boundary perturbation. We experimentally verify a predicted non-monotonic cross-over fro…
Microwave fidelity studies by varying antenna coupling
B. Köber, U. Kuhl, H. -J. Stöckmann +3
The fidelity decay in a microwave billiard is considered, where the coupling to an attached antenna is varied. The resulting quantity, coupling fidelity, is experimentally studied…
Singular statistics revised
Timur Tudorovskiy, Ulrich Kuhl, Hans-Juergen Stoeckmann
In the paper we analyze the "singular statistics" of pseudointegrable Seba billiards and show that taking into account growing number of resonances one observes the transition from…
Fidelity amplitude of the scattering matrix in microwave cavities
R. Schaefer, T. Gorin, T. H. Seligman +1
The concept of fidelity decay is discussed from the point of view of the scattering matrix, and the scattering fidelity is introduced as the parametric cross-correlation of a given…
