Wave packet autocorrelation functions for quantum hard-disk and hard-sphere billiards in the high-energy, diffraction regime
Arseni Goussev, J. R. Dorfman
We consider the time evolution of a wave packet representing a quantum particle moving in a geometrically open billiard that consists of a number of fixed hard-disk or hard-sphere…

Lyapunov Spreading of Semi-classical Wave Packets for the Lorentz Gas: Theory and Applications
Arseni Goussev, J. R. Dorfman
We consider the quantum mechanical propagator for a particle moving in a -dimensional Lorentz gas, with fixed, hard sphere scatterers. To evaluate this propagator in the semi-cl…
