Learning second order coupled differential equations that are subject to non-conservative forces

Roger Alexander Müller, Jonathan Laflamme-Janssen, Jaime Camacaro +1

In this article we address the question whether it is possible to learn the differential equations describing the physical properties of a dynamical system, subject to non-conserva…

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…

Bromophenyl functionalization of carbon nanotubes : an ab initio study

Jason Beaudin, Jonathan Laflamme Janssen, Nicholas D. M. Hine +2

We study the thermodynamics of bromophenyl functionalization of carbon nanotubes with respect to diameter and metallic/insulating character using density-functional theory (DFT). O…

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…
