Electron-phonon interactions from first principles

F Giustino - Reviews of Modern Physics, 2017 - APS
This article reviews the theory of electron-phonon interactions in solids from the point of view
of ab initio calculations. While the electron-phonon interaction has been studied for almost a …

First-principles calculations of charge carrier mobility and conductivity in bulk semiconductors and two-dimensional materials

One of the fundamental properties of semiconductors is their ability to support highly tunable
electric currents in the presence of electric fields or carrier concentration gradients. These …

The transient localization scenario for charge transport in crystalline organic materials

S Fratini, D Mayou, S Ciuchi - Advanced Functional Materials, 2016 - Wiley Online Library

The Bethe–Salpeter equation in chemistry: relations with TD-DFT, applications and challenges

X Blase, I Duchemin, D Jacquemin - Chemical Society Reviews, 2018 - pubs.rsc.org
We review the many-body Green's function Bethe–Salpeter equation (BSE) formalism that is
rapidly gaining importance for the study of the optical properties of molecular organic …

Going beyond the vertical approximation with time‐dependent density functional theory

F Santoro, D Jacquemin - Wiley Interdisciplinary Reviews …, 2016 - Wiley Online Library
Since two decades, time‐dependent density functional theory (TD‐DFT) has been in the
limelight due to its noteworthy efficiency. Indeed, in many cases, TD‐DFT provides accurate …

Cubic-Scaling All-Electron GW Calculations with a Separable Density-Fitting Space–Time Approach

I Duchemin, X Blase - Journal of Chemical Theory and …, 2021 - ACS Publications
We present an implementation of the GW space–time approach that allows cubic-scaling all-
electron calculations with standard Gaussian basis sets without exploiting any localization or …

Lattice dynamics and electron-phonon coupling calculations using nondiagonal supercells

JH Lloyd-Williams, B Monserrat - Physical Review B, 2015 - APS
We study the direct calculation of total energy derivatives for lattice dynamics and electron-
phonon coupling calculations using supercell matrices with nonzero off-diagonal elements …

Many-body effects on the zero-point renormalization of the band structure

G Antonius, S Poncé, P Boulanger, M Côté, X Gonze - Physical Review Letters, 2014 - APS
We compute the zero-point renormalization (ZPR) of the optical band gap of diamond from
many-body perturbation theory using the perturbative G 0 W 0 approximation as well as …

Dynamical and anharmonic effects on the electron-phonon coupling and the zero-point renormalization of the electronic structure

G Antonius, S Poncé, E Lantagne-Hurtubise, G Auclair… - Physical Review B, 2015 - APS
The renormalization of the band structure at zero temperature due to electron-phonon
