Polaronic Enhancement of Second-Harmonic Generation in Lithium Niobate
Agnieszka L. Kozub, Arno Schindlmayr, Uwe Gerstmann +1
Density-functional theory within a Berry-phase formulation of the dynamical polarization is used to determine the second-order susceptibility of lithium niobate (LiNbO$_3…
Analytic evaluation of the electronic self-energy in the GW approximation for two electrons on a sphere
Arno Schindlmayr
The GW approximation for the electronic self-energy is an important tool for the quantitative prediction of excited states in solids, but its mathematical exploration is hampered b…
First-principles calculation of electronic excitations in solids with SPEX
Arno Schindlmayr, Christoph Friedrich, Ersoy Sasioglu +1
We describe the software package SPEX, which allows first-principles calculations of quasiparticle and collective electronic excitations in solids using techniques from many-body p…
Optical conductivity of metals from first principles
Arno Schindlmayr
A computational method to obtain optical conductivities from first principles is presented. It exploits a relation between the conductivity and the complex dielectric function, whi…
Efficient implementation of the GW approximation within the all-electron FLAPW method
Christoph Friedrich, Stefan Blügel, Arno Schindlmayr
We present an implementation of the GW approximation for the electronic self-energy within the full-potential linearized augmented-plane-wave (FLAPW) method. The algorithm uses an…
Wannier-function approach to spin excitations in solids
Ersoy Sasioglu, Arno Schindlmayr, Christoph Friedrich +2
We present a computational scheme to study spin excitations in magnetic materials from first principles. The central quantity is the transverse spin susceptibility, from which the…
