Constant Matrix Element Approximation to Time-Resolved Angle-Resolved Photoemission Spectroscopy
We discuss several issues associated with employing a constant matrix element approximation for the coupling of light to multiband electrons in the context of time-resolved angle-resolved photoemission spectroscopy (TR-ARPES). In particular, we demonstrate that the “constant matrix element approxima...
