Uniform approximations for non-generic bifurcation scenatios including bifurcations of ghost orbits
T. Bartsch, J. Main, G. Wunner
Gutzwiller's trace formula allows interpreting the density of states of a classically chaotic quantum system in terms of classical periodic orbits. It diverges when periodic orbits…

Significance of Ghost Orbit Bifurcations in Semiclassical Spectra
T. Bartsch, J. Main, G. Wunner
Gutzwiller's trace formula for the semiclassical density of states in a chaotic system diverges near bifurcations of periodic orbits, where it must be replaced with uniform approxi…
