Periodic orbit theory for the Hénon-Heiles system in the continuum region
J. Kaidel, P. Winkler, M. Brack
We investigate the resonance spectrum of the Hénon-Heiles potential up to twice the barrier energy. The quantum spectrum is obtained by the method of complex coordinate rotation. W…

Uniform approximations for pitchfork bifurcation sequences
J. Kaidel, M. Brack
In non-integrable Hamiltonian systems with mixed phase space and discrete symmetries, sequences of pitchfork bifurcations of periodic orbits pave the way from integrability to chao…

On the canonically invariant calculation of Maslov indices
M. Pletyukhov, M. Brack
After a short review of various ways to calculate the Maslov index appearing in semiclassical Gutzwiller type trace formulae, we discuss a coordinate-independent and canonically in…
