Orbital symmetry and the optical response of single-layer monochalcogenides
Gabriel Antonius, Diana Y. Qiu, Steven G. Louie
The absorption spectra of single-layer GaSe and GaTe in the hexagonal phase feature exciton peaks with distinct polarization selectivity. We investigate these distinct features fro…
Quasiparticles and phonon satellites in spectral functions of semiconductors and insulators: Cumulants applied to full first principles theory and Fröhlich polaron
Jean Paul Nery, Philip B. Allen, Gabriel Antonius +3
The electron-phonon interaction causes thermal and zero-point motion shifts of electron quasiparticle (QP) energies . Other consequences of interactions, visible in angle-r…
Theory of Exciton-Phonon Coupling
Gabriel Antonius, Steven G. Louie
The effects of the electron-phonon interaction on optical excitations can be understood in terms of exciton-phonon coupling, and require a careful treatment in low-dimensional mate…
