Controlling Ultrafast Excitations in Germanium:The Role of Pump-Pulse Parameters and Multi-Photon Resonances
Amir Eskandari-asl, Adolfo Avella
We employ the Dynamical Projective Operatorial Approach (DPOA) to investigate the ultrafast optical excitations of germanium under intense, ultrashort pump pulses. The method has v…

Generalized Linear Response Theory for Pumped Systems and its Application to Transient Optical Properties
Amir Eskandari-asl, Adolfo Avella
We derive the two-time linear response theory for out-of-equilibrium pumped systems, generic pump-probe delays and probe frequencies. Such a theory enormously simplifies the numeri…
