+2SOSEX self-energy made positive semi-definite
Fabien Bruneval, Arno Förster, Yaroslav Pavlyukh
The formulation of vertex corrections beyond the approximation within the framework of perturbation theory is a subtle and challenging task, which accounts for the wide variet…
Femtosecond dynamics of correlated many-body states in C fullerenes
Sergey Usenko, Michael Schüler, Armin Azima +7
Fullerene complexes may play a key role in the design of future molecular electronics and nanostructured devices with potential applications in light harvesting using organic solar…
Angle-resolved time delay in photoemission
Jonas Wätzel, Andrey Moskalenko, Yaroslav Pavlyukh +1
We investigate theoretically the relative time delay of photoelectrons originating from different atomic subshells of noble gases. This quantity was measured via attosecond streaki…
Angle-resolved time delay in photoemission of neon
J. Wätzel, A. S. Moskalenko, Y. Pavlyukh +1
We investigate theoretically the relative time delay of photoelectrons originating from the different subshells (2s and 2p) of neon. This quantity was measured via attosecond strea…
Attosecond tracking of light absorption and refraction in fullerenes
A. S. Moskalenko, Y. Pavlyukh, J. Berakdar
The collective response of matter is ubiquitous and widely exploited, e.g. in plasmonic, optical and electronic devices. Here we trace on an attosecond time scale the birth of coll…
Optical absorption spectra of finite systems from a conserving Bethe-Salpeter equation approach
George Pal, Yaroslav Pavlyukh, Wolfgang Hübner +1
We present a method for computing optical absorption spectra by means of a Bethe-Salpeter equation approach, which is based on a conserving linear response calculation for electron…
