One-step theory of photoelectron escape time: Attosecond spectroscopy of Mg(0001)

A theory of photoelectron escape time τ from crystals is presented that combines the one-step photoemission theory with the Wigner delay. Equations are formally derived and illustrated with an exactly solvable model. An ab initio implementation with the augmented-plane-wave-based scattering method i...
