Gauge invariance in the interaction between atoms and few-cycle laser pulses

  • 1. Institute of Physics and Astronomy, University of Aarhus, 8000 Aarhus C (Denmark)

Description

It is shown that certain unitary gauge operations that are normally of negligible importance in the theory of laser-atom interactions become significant for pulses containing only a few cycles, and it is discussed how to make gauge invariant predictions in general, and in particular in the velocity and length gauges, and in the Henneberger frame
