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…

Diagrammatic expansion for positive density-response spectra: Application to the electron gas
A. -M. Uimonen, G. Stefanucci, Y. Pavlyukh +1
In a recent paper [Phys. Rev. B 90, 115134 (2014)] we put forward a diagrammatic expansion for the self-energy which guarantees the positivity of the spectral function. In this wor…
