dc.description.abstract | We present a generalized velocity gauge form of the relativistic laser-matter interaction. In comparison with
the (equivalent) regular minimal coupling description, this form of light-matter interaction results in superior
convergence properties for the numerical solution of the time-dependent Dirac equation. This applies both to the
numerical treatment and, more importantly, to the multipole expansion of the laser field. The advantages of the
alternative gauge is demonstrated in hydrogen by studies of the dynamics following the impact of superintense
laser pulses of extreme ultraviolet wavelengths and subfemtosecond duration. | language |
