Precise effective masses from density functional perturbation theory
Jonathan Laflamme Janssen, Yannick Gillet, Samuel Poncé +3
The knowledge of effective masses is a key ingredient to analyze numerous properties of semiconductors, like carrier mobilities, (magneto-)transport properties, or band extrema cha…
Temperature dependence of the electronic structure of semiconductors and insulators
Samuel Poncé, Yannick Gillet, Jonathan Laflamme Janssen +3
The renormalization of electronic eigenenergies due to electron-phonon coupling is sizable in many materials with light atoms. This effect, often neglected in ab-initio calculation…
The temperature dependence of electronic eigenenergies in the adiabatic harmonic approximation
Samuel Poncé, Gabriel Antonius, Yannick Gillet +5
The renormalization of electronic eigenenergies due to electron-phonon interactions (temperature dependence and zero-point motion effect) is important in many materials. We address…
Efficient dielectric matrix calculations using the Lanczos algorithm for fast many-body implementations
Jonathan Laflamme Janssen, Bruno Rousseau, Michel Côté
We present a implementation that assesses the two major bottlenecks of traditional plane-waves implementations, the summations over conduction states and the inversion of…
Electron-phonon coupling in the C60 fullerene within the many-body GW approach
Carina Faber, Jonathan Laflamme Janssen, Michel Côté +2
We study the electron-phonon coupling in the C60 fullerene within the first-principles GW approach, focusing on the lowest unoccupied t1u three-fold electronic state which is relev…
