Fictitious time wave packet dynamics: II. Hydrogen atom in external fields
T. Fabčič, J. Main, G. Wunner
In the preceding paper [T. Fabcic et al., preprint] "restricted Gaussian wave packets" were introduced for the regularized Coulomb problem in the four-dimensional Kustaanheimo-Stie…

Fictitious time wave packet dynamics: I. Nondispersive wave packets in the quantum Coulomb problem
T. Fabčič, J. Main, G. Wunner
Nondispersive wave packets in a fictitious time variable are calculated analytically for the field-free hydrogen atom. As is well known by means of the Kustaanheimo-Stiefel transfo…
