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…

Coupled Microwave Billiards as a Model for Symmetry Breaking
H. Alt, C. I. Barbosa, H. -D. Graef +5
Two superconducting microwave billiards have been electromagnetically coupled in a variable way. The spectrum of the entire system has been measured and the spectral statistics ana…
