Response functions of semiconductors and insulators : from the Bethe-Salpeter equation to time-dependent density functional theory

THz-driven coherent polaron dynamics exhibits distinguishing features: room temperature coherent oscillations at ω LO longer than 1 ps in both single crystals and thin

The characterization of compact composition operators on the Dirichlet space in terms of Carleson measures can be found in [3, 12, 17].. Such a measure has the following equiv-

Les résultats obtenus lors de l’utilisation du Pd(II) comme catalyseur pour la réaction d’hétérocyclisation réductive de la 2’-nitrochalcone, montrent qu’on obtient

systems is possible via spin-orbit coupling in the excited intermediate state1. The scattering cross section is proportional to the spin correlation function and results in

Using the exact one-particle Green’s function in the BSE approach within the static GW approximation also leads to a number of additional excitations, all of them being spurious
