Photoinduced dynamics of organic molecules using nonequilibrium Green's functions with second-Born, , -matrix and three-particle ladder correlations
Yaroslav Pavlyukh, Enrico Perfetto, Gianluca Stefanucci
The ultrafast hole dynamics triggered by the photoexcitation of molecular targets is a highly correlated process even for those systems, like organic molecules, having a weakly cor…
Dynamically screened vertex correction to
Y. Pavlyukh, G. Stefanucci, R. van Leeuwen
Diagrammatic perturbation theory is a powerful tool for the investigation of interacting many-body systems, the self-energy operator encoding all the variety of scattering proc…
Ultrafast coupled charge and spin dynamics in strongly correlated NiO
Konrad Gillmeister, Denis Golež, Cheng-Tien Chiang +5
Charge excitations across an electronic band gap play an important role in opto-electronics and light harvesting. In contrast to conventional semiconductors, studies of above-band-…
A functional approach to the electronic and bosonic dynamics of many-body systems perturbed with an arbitrary strong electron-boson interaction
Andrea Marini, Yaroslav Pavlyukh
We present a formal derivation of the many-body perturbation theory for a system of electrons and bosons subject to a nonlinear electron-boson coupling. The interaction is treated…
Accessing electronic correlations by half-cycle pulses and time-resolved spectroscopy
Y. Pavlyukh, J. Berakdar
Ultrashort non-resonant electromagnetic pulses applied to effective one-electron systems may operate on the electronic state as a position or momentum translation operator. As deri…
Single and double electron emission: combination of projection operator and nonequilibrium Green's function approaches
Y. Pavlyukh, M. Schüler, J. Berakdar
This work provides a unified theoretical treatment of the single and correlated double-electron emission from a general electronic system. Using Feshbach projection method, the sta…
