Role of Resonant -Points in the Transient Optical Response of Pumped Germanium
Amir Eskandari-asl, Giacomo Inzani, Matteo Lucchini +1
Pump-induced transient optical properties combine contributions from electronic states throughout the Brillouin zone, but the relative relevance of off-resonant and l-photon resona…
Time-resolved ARPES in pumped excitonic systems: Floquet physics induced by excitonic fields
Amir Eskandari-asl, Adolfo Avella
We develop a theoretical framework based on the Dynamical Projective Operatorial Approach (DPOA) to study the time- and angle-resolved photoemission spectroscopy (TR-ARPES) of pump…
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…
Magneto-optical Kerr effect in pump-probe setups
Amir Eskandari-asl, Adolfo Avella
We develop a general theoretical framework for computing the time-resolved magneto-optical Kerr effect in ultrafast pump-probe setups, formulated within the Dynamical Projective Op…
Which Rope Breaks? A Study of Tension Distribution in Multi-Rope Systems
Amir Eskandari-asl, Roberto De Luca
We investigate the tension distribution in systems of mass-less ropes under different loading conditions. For a two-rope system, we demonstrate how the breaking scenario depends on…
Controlling photo-excited electron-spin by light-polarization in ultrafast-pumped altermagnets
Amir Eskandari-asl, Jorge I. Facio, Oleg Janson +2
Altermagnets (AMs) constitute a novel class of spin-compensated materials in which the symmetry connecting opposite-spin sublattices involves a spatial rotation. Here, we uncover a…
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…
TR-ARPES Signal in Pumped Semiconductors within Dynamical Projective Operatorial Approach (DPOA)
Amir Eskandari-asl, Adolfo Avella
In this manuscript, after discussing in detail the internals of our recently developed method, the dynamical projective operatorial approach (DPOA), we provide the framework to app…
Field-driven attosecond photoinjection dynamics in semiconductors
Giacomo Inzani, Lyudmyla Adamska, Amir Eskandari-asl +12
The route towards manipulation of the optoelectronic properties of matter beyond the current limits of electronics starts from a comprehensive study of the ultrafast dynamics trigg…
Local properties of the t-J model in a two-pole approximation within COM
Amir Eskandari-asl, Adolfo Avella
In this work, we study the t-J model using a two-pole approximation within the composite operator method. We choose a basis of two composite operators -- the constrained electrons…
Interplay of Electron-Electron and Electron-Phonon Interactions in Molecular Junctions
Amir Eskandari-asl
In this work we consider a current carrying molecular junction with both electron-phonon and electron-electron interactions taken into account. After performing Lang-Firsov transfo…
Some Static Properties of Slinky
Amir Eskandari-asl
In this paper we use a simple discrete model for Slinky to explore some of its static properties. We derive some relations for vertically and U-shaped suspended Slinkies, based on…
