Multi-scale calculation of light-induced structural changes in low-angle twisted bilayer WSe

Rafael R. Del Grande, David A. Strubbe

Exciton-phonon interactions in transition metal dichalcogenides (TMD) are strong and lead to phenomena such as coherent phonon generation. When stacked and twisted, their propertie…

Analyzing Band Gaps in Ensemble Density Functional Theory using Thermodynamic Limits of Finite One-Dimensional Model Systems

Gregory G. V. Kenning, Remi J. Leano, David A. Strubbe

Ensemble Density Functional Theory (EDFT) is a promising extension to Density Functional Theory (DFT) for calculating excited states. While Kohn-Sham eigenvalue differences underes…

How to choose efficiently the size of the Bethe-Salpeter Equation Hamiltonian for accurate exciton calculations on supercells

Rafael R. Del Grande, David A. Strubbe

The Bethe-Salpeter Equation (BSE) is the workhorse method to study excitons in materials. The BSE Hamiltonian size, which depends on how many valence-to-conduction band transitions…

Revisiting ab-initio excited state forces from many-body Green's function formalism: approximations and benchmark

Rafael R. Del Grande, David A. Strubbe

Ab initio techniques for studying the optical and vibrational properties of materials are well-established, but only a few recent studies have focused on the interaction between ex…
