Tests of the Porter-Thomas Distribution for Reduced Partial Neutron Widths
H. -L. Harney, H. A. Weidenmüller
Given N data points drawn from a chi-square distribution, we use Bayesian inference to determine most likely values and N-dependent confidence intervals for the width sigma and the…
On The Gaussian Approximation To Bayesian Posterior Distributions
Christoph Fuhrmann, Hanns Ludwig Harney, Klaus Harney +1
The present article derives the minimal number of observations needed to consider a Bayesian posterior distribution as Gaussian. Two examples are presented. Within one of them,…
Scattering Experiments with Microwave Billiards at an Exceptional Point under Broken Time Reversal Invariance
S. Bittner, B. Dietz, H. L. Harney +3
Scattering experiments with microwave cavities were performed and the effects of broken time-reversal invariance (TRI), induced by means of a magnetized ferrite placed inside the c…
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…
Cross-Section Fluctuations in Chaotic Scattering
B. Dietz, H. L. Harney, A. Richter +2
For the theoretical prediction of cross-section fluctuations in chaotic scattering, the cross-section autocorrelation function is needed. That function is not known analytically. U…
Induced Violation of Time-Reversal Invariance in the Regime of Weakly Overlapping Resonances
B. Dietz, T. Friedrich, H. L. Harney +5
We measure the complex scattering amplitudes of a flat microwave cavity (a "chaotic billiard"). Time-reversal T-invariance is partially broken by a magnetized ferrite placed within…
