Ultraviolet optical conductivity, exciton fine-structure and dispersion of freestanding monolayer h-BN
Jinhua Hong, Alberto Guandalini, Weibin Wu +7
Excitons govern the light-matter interaction in 2D gapped materials with intrinsically large binding energies. In spite of plentiful optical measurements in the visible for semicon…
Infrared markers of topological phase transitions in quantum spin Hall insulators
Paolo Fachin, Francesco Macheda, Paolo Barone +1
Using first principles techniques, we show that infrared optical response can be used to discriminate between the topological and the trivial phases of two-dimensional quantum spin…
Excitonic effects in phonons: reshaping the graphene Kohn anomalies and lifetimes
Alberto Guandalini, Francesco Macheda, Giovanni Caldarelli +1
We develop an ab initio framework that captures the impact of electron-electron and electron-hole interactions on phonon properties. This enables the inclusion of excitonic effects…
