A spectral duality in graphs and microwave networks
Tobias Hofmann, Junjie Lu, Ulrich Kuhl +1
Quantum graphs and their experimental counterparts, microwave networks, are ideally suited to study the spectral statistics of chaotic systems. The graph spectrum is obtained from…
Weyl asymptotics: From closed to open systems
A. Potzuweit, T. Weich, S. Barkhofen +3
We present microwave experiments on the symmetry reduced 5-disk billiard studying the transition from a closed to an open system. The measured microwave reflection signal is analyz…
Measurement of the Goos-Hänchen shift in a microwave cavity
Julia Unterhinninghofen, Ulrich Kuhl, Jan Wiersig +2
We present measurements of the Goos-Hänchen shift in a two-dimensional dielectric microwave cavity. Microwave beams are generated by a suitable superposition of the spherical waves…
Quantum stress in chaotic billiards
K. -F. Berggren, D. N. Maksimov, A. F. Sadreev +3
This article reports on a joint theoretical and experimental study of the Pauli quantum-mechanical stress tensor for open two-dimensional chaotic billiards. In the ca…
Exact energy distribution function in time-dependent harmonic oscillator
Marko Robnik, Valery G. Romanovski, Hans-Juergen Stoeckmann
Following a recent work by Robnik and Romanovski (J.Phys.A: Math.Gen. {\bf 39} (2006) L35, Open Syst. & Infor. Dyn. {\bf 13} (2006) 197-222) we derive the explicit formula for the…
Fidelity freeze for a random matrix model with off--diagonal perturbation
H. -J. Stoeckmann. H. Kohler
The concept of fidelity has been introduced to characterize the stability of a quantum-mechanical system against perturbations. The fidelity amplitude is defined as the overlap int…
