Formation and interaction of resonance chains in the open 3-disk system
T. Weich, S. Barkhofen, U. Kuhl +2
In ballistic open quantum systems one often observes that the resonances in the complex-energy plane form a clear chain structure. Taking the open 3-disk system as a paradigmatic m…

Equivariant spectral asymptotics for h-pseudodifferential operators
Tobias Weich
We prove equivariant spectral asymptotics for -pseudodifferential operators for compact orthogonal group actions generalizing results of El-Houakmi and Helffer (1991) and Cassa…

Asymptotic spectral gap and Weyl law for Ruelle resonances of open partially expanding maps
Jean-François Arnoldi, Frédéric Faure, Tobias Weich
We consider a simple model of an open partially expanding map. Its trapped set K in phase space is a fractal set. We first show that there is a well defined discrete spectrum of Ru…
