Symmetries of excitons
Muralidhar Nalabothula, Davide Sangalli, Fulvio Paleari +2
Excitons, bound electron-hole pairs, are responsible for strong optical resonances near the bandgap in low-dimensional materials and wide-bandgap insulators. Although current ab in…
Excitonic response in TMD heterostructures from first-principles: impact of stacking, twisting, and interlayer distance
R. Reho, A. R. Botello-Méndez, D. Sangalli +2
Van der Waals heterostructures of two-dimensional transition metal dichalcogenides provide a unique platform to engineer optoelectronic devices tuning their optical properties via…
First-principles approach to excitons in time-resolved and angle-resolved photoemission spectra
E. Perfetto, D. Sangalli, A. Marini +1
We show that any {\em quasi-particle} or GW approximation to the self-energy does not capture excitonic features in time-resolved (TR) photoemission spectroscopy. In this work we p…
