Semiclassical approximations for Hamiltonians with operator-valued symbols
Hans-Michael Stiepan, Stefan Teufel
We consider the semiclassical limit of quantum systems with a Hamiltonian given by the Weyl quantization of an operator valued symbol. Systems composed of slow and fast degrees of…

The Selberg trace formula for Dirac operators
Jens Bolte, Hans-Michael Stiepan
We examine spectra of Dirac operators on compact hyperbolic surfaces. Particular attention is devoted to symmetry considerations, leading to non-trivial multiplicities of eigenvalu…
