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

Use of Harmonic Inversion Techniques in the Periodic Orbit Quantization of Integrable Systems
K. Weibert, J. Main, G. Wunner
Harmonic inversion has already been proven to be a powerful tool for the analysis of quantum spectra and the periodic orbit orbit quantization of chaotic systems. The harmonic inve…
