Self-consistent solution of Hedin's equations: semiconductors/insulators
Andrey L. Kutepov
The band gaps of a few selected semiconductors/insulators are obtained from the self-consistent solution of the Hedin's equations. Two different schemes to include the vertex corre…
Strength and scales of itinerant spin fluctuations in 3d paramagnetic metals
Aleksander L. Wysocki, Andrey Kutepov, Vladimir P. Antropov
The full spin density fluctuations (SDF) spectra in 3d paramagnetic metals are analyzed from first principles using the linear response technique. Using the calculated complete wav…
Linearized self-consistent quasiparticle GW method: Application to semiconductors and simple metals
Andrey L. Kutepov, Viktor S. Oudovenko, Gabriel Kotliar
We present a code implementing the linearized self-consistent quasiparticle GW method (scQPGW) in the LAPW basis. Our approach is based on the linearization of the self-energy arou…
Electronic structure of Na, K, Si, and LiF from self-consistent solution of Hedin's equations including vertex corrections
Andrey L. Kutepov
A few self-consistent schemes to solve the Hedin equations are presented. They include vertex corrections of different complexity. Commonly used quasiparticle approximation for the…
