Polarons in two-dimensional atomic crystals
Weng Hong Sio, Feliciano Giustino
The polaron is the archetypal example of a quasiparticle emerging from the interaction between fermionic and bosonic fields in quantum field theory. In crystalline solids, polarons…
Electron-phonon physics from first principles using the EPW code
Hyungjun Lee, Samuel Poncé, Kyle Bushick +13
EPW is an open-source software for calculations of electron-phonon interactions and related materials properties. The code combines density functional perturba…
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…
Ab initio theory of polarons: formalism and applications
Weng Hong Sio, Carla Verdi, Samuel Ponce +1
We develop a theoretical and computational framework to study polarons in semiconductors and insulators from first principles. Our approach provides the formation energy, excitatio…
