Unified description of exciton, phonon and plasmon dispersions in 2D materials from an optical conductivity approximation
Alberto Guandalini, Andrea Ferretti, Daniele Varsano +2
The modified Coulomb interaction in two-dimensional (2D) materials gives rise to unique, non-analytic low-momentum dispersions of excitons, phonons, and plasmons. Here, we describe…

A viable and accurate route to GW simulations of metals and doped semiconductors
Giacomo Sesti, Alberto Guandalini, Andrea Ferretti +4
In this work we present an efficient and fully ab-initio approach for the calculation of the screened Coulomb potential, specifically designed for two dimensional (2D) and three di…
