On determination of statistical properties of spectra from parametric level dynamics
Miroslaw Hardej, Marek Kus, Cezary Gonera +1
We analyze an approach aiming at determining statistical properties of spectra of time-periodic quantum chaotic system based on the parameter dynamics of their quasienergies. In pa…
Random unistochastic matrices
K. Zyczkowski, W. Slomczynski, M. Kus +1
An ensemble of random unistochastic (orthostochastic) matrices is defined by taking squared moduli of elements of random unitary (orthogonal) matrices distributed according to the…
Classical 1D maps, quantum graphs and ensembles of unitary matrices
Prot Pakonski, Karol Zyczkowski, Marek Kus
We study a certain class of classical one dimensional piecewise linear maps. For these systems we introduce an infinite family of Markov partitions into equal cells. The symbolic d…
Level Dynamics and Universality of Spectral Fluctuations
Peter Braun, Sven Gnutzmann, Fritz Haake +2
The spectral fluctuations of quantum (or wave) systems with a chaotic classical (or ray) limit are mostly universal and faithful to random-matrix theory. Taking up ideas of Pechuka…
