Beyond the Heisenberg time: Semiclassical treatment of spectral correlations in chaotic systems with spin 1/2
Petr Braun
The two-point correlation function of chaotic systems with spin 1/2 is evaluated using periodic orbits. The spectral form factor for all times thus becomes accessible. Equivalence…

Parametrization of spin-1 classical states
Olivier Giraud, Petr Braun, Daniel Braun
We give an explicit parametrization of the set of mixed quantum states and of the set of mixed classical states for a spin--1. Classical states are defined as states with a positiv…

Correlations between spectra with different symmetry: any chance to be observed?
P. Braun, F. Leyvraz, T. H. Seligman
A standard assumption in quantum chaology is the absence of correlation between spectra pertaining to different symmetries. Doubts were raised about this statement for several reas…
