Inclusion of Diffraction Effects in the Gutzwiller Trace Formula
G. Vattay, A. Wirzba, P. E. Rosenqvist
The Gutzwiller trace formula is extended to include diffraction effects. The new trace formula involves periodic rays which have non-geometrical segments as a result of diffraction…

Differential equations to compute corrections of the trace formula
Gabor Vattay
In this paper a new method for computation of higher order corrections to the saddle point approximation of the Feynman path integral is discussed. The saddle point approximation l…
