Gage-equivalent forms of the Schroedinger equation for a hydrogenlike atom in a time-dependent electric field

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/120417Several gage-equivalent forms (including some novel ones) of the Schroedinger equation for a hydrogenlike atom in a time-dependent electric field of a laser pulse are presented. These forms allow to develop a perturbation theory for both small and rather large intensities of the electromagnetic field.10 pages, submitted to Fundamental and Applied MathematicsAtomic PhysicsOpticsGage-equivalent forms of the Schroedinger equation for a hydrogenlike atom in a time-dependent electric fieldtext
