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…

Solvers for the Hermitian and the pseudo-Hermitian Bethe-Salpeter equation in the Yambo code: Implementation and Performance
Petru Milev, Blanca Mellado-Pinto, Muralidhar Nalabothula +8
We analyze the performance of two strategies in solving the structured eigenvalue problem deriving from the Bethe-Salpeter equation (BSE) in condensed matter physics. The BSE matri…

Origin of interlayer exciton-phonon coupling in 2D heterostructures
Muralidhar Nalabothula, Ludger Wirtz, Sven Reichardt
The coupling between excitons and phonons across adjacent layers has been experimentally observed in various heterostructures of layered materials. Yet the precise mechanism underl…
