Theory of excitonic polarons: From models to first-principles calculations
Zhenbang Dai, Chao Lian, Jon Lafuente-Bartolome +1
Excitons are neutral excitations that are composed of electrons and holes bound together by their attractive Coulomb interaction. The electron and the hole forming the exciton also…
Excitonic polarons and self-trapped excitons from first-principles exciton-phonon couplings
Zhenbang Dai, Chao Lian, Jon Lafuente-Bartolome +1
Excitons consist of electrons and holes held together by their attractive Coulomb interaction. Although excitons are neutral excitations, spatial fluctuations in their charge densi…
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…
