The R-matrix with Time dependence approach RMT for atomic and molecular dynamics in intense fields

The R-matrix with time-dependence approach aims to solve the time-dependent Schrodinger equation for general multi-electron atoms and molecules interacting with intense laser light. In the last few years, we have generalised the approach to the treatment of arbitrarily polarised laser light, to the description of atoms within the Breit-Pauli approximation, and to the description of molecular dynamics. We will illustrate these developments through a demonstration of dynamics driven by the spin-orbit interaction, through verification of the ratio of emission of co- and counter-rotating electrons in circularly polarised light fields, and through the intensity dependence of photoionization of water.
