... equilibrium condition, the conventional Fermi-Golden rule dealing the electron-phonon coupling thus does not work. Under such a non-equilibrium condition, the real-time propagation must be treated ... electronic excitations [5]. In addition to the ‘real-time propagation’ of electrons [4], we treat ionic motion within Ehrenfest approximation [6]. Since ion dynamics requires typical simulation...
