Periodic Orbit Quantization beyond Semiclassics
Gabor Vattay, Per E. Rosenqvist
A quantum generalization of the semiclassical theory of Gutzwiller is given. The new formulation leads to systematic orbit-by-orbit inclusion of higher contributions to the…

Periodic Orbit Theory of Diffraction
Gábor Vattay, Andreas Wirzba, Per E. Rosenqvist
An extension of the Gutzwiller trace formula is given that includes diffraction effects due to hard wall scatterers or other singularities. The new trace formula involves periodic…
