SternheimerGW: a program for calculating GW quasiparticle band structures and spectral functions without unoccupied states
Martin Schlipf, Henry Lambert, Nourdine Zibouche +1
The SternheimerGW software uses time-dependent density-functional perturbation theory to evaluate GW quasiparticle band structures and spectral functions for solids. Both the Green…
Imeall: A Computational Framework for the Calculation of the Atomistic Properties of Grain Boundaries
Henry Lambert, Adam Fekete, James R Kermode +1
We describe the \texttt{Imeall} package for the calculation and indexing of atomistic properties of grain boundaries in materials. The package provides a structured database for th…
Origin of superconductivity and latent charge density wave in NbS
Christoph Heil, Samuel Poncé, Henry Lambert +3
We elucidate the origin of the phonon-mediated superconductivity in 2-NbS using the ab initio anisotropic Migdal-Eliashberg theory including Coulomb interactions. We demonst…
Ab initio calculation of spin fluctuation spectra using time dependent density functional perturbation theory, planewaves, and pseudopotentials
Kun Cao, Henry Lambert, Paolo G. Radaelli +1
We present an implementation of time-dependent density functional perturbation theory for spin fluctuations, based on planewaves and pseudopotentials. We compute the dynamic spin s…
On the combined use of GW approximation and cumulant expansion in the calculations of quasiparticle spectra: The paradigm of Si valence bands
Branko Gumhalter, Vjekoslav Kovač, Fabio Caruso +2
Since the earliest implementations of the various GW approximations and cumulant expansion in the calculations of quasiparticle propagators and spectra, several attempts have been…
Electron-phonon interaction and pairing mechanism in superconducting Ca-intercalated bilayer graphene
E. R. Margine, Henry Lambert, Feliciano Giustino
Using the {\it ab initio} anisotropic Eliashberg theory including Coulomb interactions, we investigate the electron-phonon interaction and the pairing mechanism in the recently-rep…
