Application of a trace formula to the spectra of flat three-dimensional dielectric resonators
S. Bittner, E. Bogomolny, B. Dietz +2
The length spectra of flat three-dimensional dielectric resonators of circular shape were determined from a microwave experiment. They were compared to a semiclassical trace formul…

PT symmetry and spontaneous symmetry breaking in a microwave billiard
S. Bittner, B. Dietz, U. Guenther +4
We demonstrate the presence of parity-time (PT) symmetry for the non-Hermitian two-state Hamiltonian of a dissipative microwave billiard in the vicinity of an exceptional point (EP…
