Uw. Rathe et al., INTENSE LASER-ATOM DYNAMICS WITH THE 2-DIMENSIONAL DIRAC-EQUATION, Journal of physics. B, Atomic molecular and optical physics, 30(15), 1997, pp. 531-539
A time-dependent numerical analysis is made of atomic wavefunctions ev
olving under the influence of laser pulses sufficiently intense that r
elativistic effects are important. The investigation utilizes the two-
dimensional Dine equation to identify relativistic effects such as the
contribution of the magnetic field and spin dynamics.
