Comparison of long-range corrected kernels and range-separated hybrids for excitons in solids
Rita Maji, Elena Degoli, Monica Calatayud +2
The most accurate theoretical method to describe excitons is the solution of the Bethe-Salpeter equation in the GW approximation (GW-BSE). However, because of its computation cost,…
Resonant optical control of the structural distortions that drive ultrafast demagnetization in CrO
Vera G. Sala, Stefano Dal Conte, Timothy A. Miller +5
We study how the color and polarization of ultrashort pulses of visible light can be used to control the demagnetization processes of the antiferromagnetic insulator CrO. W…
Ab Initio Second-Order Nonlinear Optics in Solids: Second-Harmonic Generation Spectroscopy from Time-Dependent Density-Functional Theory
Eleonora Luppi, Hannes Hübener, Valérie Véniard
We present in detail the formulation of the ab initio theory we have developed for the calculation of the macroscopic second-order susceptibility . We find a general expre…
Second-Order Nonlinear Optics from First Principles
Eleonora Luppi, Hannes Hübener, Valérie Véniard
We present a new first-principle theory for the calculation of the macroscopic second-order susceptibility chi^(2), based on the Time-Dependent Density-Functional Theory approach.…
