Time-Dependent Density-Functional Theory (TDDFT) is a well-established theoretical approach to describe and understand irradiation processes in clusters and molecules. The discretization of the electronic wave functions on a spatial grid and the use of absorbing boundary conditions allows one to study electronic emission, and in particular photoelectron spectra. However, in this scheme, the unitarity...
We apply in a schematic model a theory beyond mean-field, namely Stochastic Time-Dependent Hartree–Fock (STDHF), which includes dynamical electron–electron collisions on top of an incoherent ensemble of mean-field states by occasional 2-particle–2-hole (2p2h) jumps. The model considered here is inspired by a Lipkin–Meshkov–Glick model of Ω particles distributed into two bands of energy and coupled...
