First-principles nonequilibrium Green's function approach to transient photoabsorption: Application to atoms
E. Perfetto, A. -M. Uimonen, R. van Leeuwen +1
We put forward a first-principle NonEquilibrium Green's Function (NEGF) approach to calculate the transient photoabsorption spectrum of optically thin samples. The method can deal…
Ultra-nonlocality in density functional theory for photo-emission spectroscopy
A. -M. Uimonen, G. Stefanucci, R. van Leeuwen
We derive an exact expression for the photo-current of photo-emission spectroscopy using time-dependent current density functional theory (TDCDFT). This expression is given as an i…
Correlation effects in bistability at the nanoscale: steady state and beyond
E. Khosravi, A. -M. Uimonen, A. Stan +4
The possibility of finding multistability in the density and current of an interacting nanoscale junction coupled to semi-infinite leads is studied at various levels of approximati…
Comparative study of many-body perturbation theory and time-dependent density functional theory in the out-of-equilibrium Anderson model
A. -M. Uimonen, E. Khosravi, A. Stan +4
We study time-dependent electron transport through an Anderson model. The electronic interactions on the impurity site are included via the self-energy approximations at Hartree-Fo…
