Superiority of semiclassical over quantum mechanical calculations for a three-dimensional system
J. Main, G. Wunner, E. Atilgan +2
In systems with few degrees of freedom modern quantum calculations are, in general, numerically more efficient than semiclassical methods. However, this situation can be reversed w…

Periodic orbit quantization of chaotic systems with strong pruning
K. Weibert, J. Main, G. Wunner
The three-disk system, which for many years has served as a paradigm for the usefulness of cycle expansion methods, represents an extremely hard problem to semiclassical quantizati…
