Level density of the Hénon-Heiles system above the critical barrier Energy
M. Brack, J. Kaidel, P. Winkler +1
We discuss the coarse-grained level density of the Hénon-Heiles system above the barrier energy, where the system is nearly chaotic. We use periodic orbit theory to approximate its…

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…
