Elements of Photoionization Quantum Dynamics Methods

Elements of Photoionization Quantum Dynamics Methods focuses on the RMT approach to multiphoton quantum dynamics, which is employed to tackle the problem of laser-induced atomic dynamics. This recently developed formulation has shown the potential to become a mainstream ab initio theoretical approach, which is capable of describing the quantum dynamics of multielectron quantum systems exposed in ultrashort intense laser pulses lasting at the femtosecond timescale (∼10⁻¹⁸ sec). The method itself builds on the division-of-space concept and has evolved as an extension of the well-established atomic R-matrix method to incorporate time in its formulation. It is this way that its name was inherited, R-matrix with time incorporation (RMT), although no R-matrix appears anywhere in the formulation.
