Spectral statistics in an open parametric billiard system
TL;DR: Experimental results on the eigenfrequency statistics of a superconducting, chaotic microwave billiard containing a rotatable obstacle show deviations of the spectral fluctuations from predictions based on Gaussian orthogonal ensembles of random matrices.
Journal ArticleDOI
Inelastic electron scattering on the N = 28 isotones 48Ca, 50Ti, and 54Fe and the shape and magnitude of the M1 strength distributions

TL;DR: In this paper, an analysis of the data including all available information about Be-13, and in particular recent data from a similar experiment performed at RIKEN, has been performed.
Journal ArticleDOI
Spectral statistics and the fine structure of the electric pygmy dipole resonance in N = 82 nuclei ✩
Joachim Enders,Thomas Guhr,Andreas Heine,P. von Neumann-Cosel,V. Yu. Ponomarev,Achim Richter,Jochen Wambach +6 more
TL;DR: In this article, the statistical properties of the electric pygmy dipole resonance in four different isotones with neutron number N = 82 were studied, i.e., in between the predictions of random matrix theory for correlated and uncorrelated spectra.
Journal ArticleDOI
Spectral Properties of Dirac Billiards at the van Hove Singularities.
TL;DR: It is demonstrated in this Letter that the ratio distributions provide suitable measures for measuring the spectral properties of superconducting microwave resonators containing circular scatterers on a triangular grid, so-called Dirac billiards.
