Effects of self-consistency and plasmon-pole models on GW calculations for closed-shell molecules

Johannes Lischner, Sahar Sharifzadeh, Jack Deslippe +2

We present theoretical calculations of quasiparticle energies in closed-shell molecules using the GW method. We compare three different approaches: a full-frequency (FF-$G…

Numerical integration for ab initio many-electron self energy calculations within the GW approximation

Fang Liu, Lin Lin, Derek Vigil-Fowler +8

We present a numerical integration scheme for evaluating the convolution of a Green's function with a screened Coulomb potential on the real axis in the GW approximation of the sel…

Satellite structures in the spectral functions of semiconductor quantum well two-dimensional electron gases: a GW plus cumulant study

Johannes Lischner, Derek Vigil-Fowler, Steven G. Louie

We present theoretical calculations for the spectral functions and single-particle densities of states of the two-dimensional electron gas in semiconductor quantum wells at differe…

Effect of spin fluctuations on quasiparticle excitations: first-principles theory and application to sodium and lithium

Johannes Lischner, Timur Bazhirov, Allan H. MacDonald +2

We present first-principles calculations for quasiparticle excitations in sodium and lithium including the effects of charge and spin fluctuations. We employ the Overhauser-Kukkone…
