In this pre-print, Feiguin et al. present an alternative solution to understanding the “scattering cross-section” of electromagnetic fields, using a “time-dependent momentum-resolved” approach. This method “does not require a full set” of quantum states to solve. The authors argue that “this powerful formulation overcomes all the hurdles imposed by previous methods.”
