Ab initio self-consistent many-body theory of polarons at all couplings
Jon Lafuente-Bartolome, Chao Lian, Weng Hong Sio +3
We present a theoretical framework to describe polarons from first principles within a many-body Green's function formalism. Starting from a general electron-phonon Hamiltonian, we…
Unified approach to polarons and phonon-induced band structure renormalization
Jon Lafuente-Bartolome, Chao Lian, Weng Hong Sio +3
Ab initio calculations of the phonon-induced band structure renormalization are currently based on the perturbative Allen-Heine theory and its many-body generalizations. These appr…
Unified ab initio description of Fröhlich electron-phonon interactions in two-dimensional and three-dimensional materials
Weng Hong Sio, Feliciano Giustino
\textit{Ab initio} calculations of electron-phonon interactions including the polar Fröhlich coupling have advanced considerably in recent years. The Fröhlich electron-phonon matri…
