Exceptional Points in a Microwave Billiard with Time-Reversal Invariance Violation
B. Dietz, H. L. Harney, O. N. Kirillov +3
We report on the experimental study of an exceptional point (EP) in a dissipative microwave billiard with induced time-reversal invariance (T) violation. The associated two-state H…
Quantum Chaotic Scattering in Microwave Resonators
B. Dietz, T. Friedrich, H. L. Harney +4
In a frequency range where a microwave resonator simulates a chaotic quantum billiard, we have measured moduli and phases of reflection and transmission amplitudes in the regimes o…
Time Reversal and Exceptional Points
H. L. Harney, W. D. Heiss
Eigenvectors of decaying quantum systems are studied at exceptional points of the Hamiltonian. Special attention is paid to the properties of the system under time reversal symmetr…
The Chirality of Exceptional Points
W. D. Heiss, H. L. Harney
Exceptional points are singularities of the spectrum and wave functions which occur in connection with level repulsion. They are accessible in experiments using dissipative systems…
The Impact of Isospin Breaking on the Distribution of Transition Probabilities
C. I. Barbosa, T. Guhr, H. L. Harney
In the present paper we investigate the effect of symmetry breaking in the statistical distributions of reduced transition amplitudes and reduced transition probabilities. These qu…
Analyzing symmetry breaking within a chaotic quantum system via Bayesian inference
C. I. Barbosa, H. L. Harney
Bayesian inference is applied to the level fluctuations of two coupled microwave billiards in order to extract the coupling strength. The coupled resonators provide a model of a ch…
