Nonlinear electron-phonon interactions from first principles
Zhenbang Dai, Feliciano Giustino
Electron-phonon interactions underpin a variety of phenomena, ranging from transport and superconductivity to polarons and ultrafast carrier dynamics. Despite being one of the most…
Watching Polarons Form in Real Time
Victor Garcia-Herrero, Christoph Emeis, Zhenbang Dai +3
Polaron formation in pump-probe experiments is an inherently non-equilibrium phenomenon, driven by the ultrafast coupled dynamics of electrons and phonons, and culminating in the e…
Polarons from first principles
Zhenbang Dai, Jon Lafuente-Bartolome, Feliciano Giustino
This article reviews recent theoretical developments in the ab initio study of polarons in materials. The polaron is an emergent quasiparticle that arises from the interaction betw…
Comparison between first-principles supercell calculations of polarons and the ab initio polaron equations
Zhenbang Dai, Donghwan Kim, Jon Lafuente-Bartolome +1
Polarons are composite quasiparticles formed by excess charges and the accompanying lattice distortions in solids, and play a critical role in transport, optical, and catalytic pro…
Identification of large polarons and exciton polarons in rutile and anatase polymorphs of titanium dioxide
Zhenbang Dai, Feliciano Giustino
Titanium dioxide (TiO2) is a wide-gap semiconductor with numerous applications in photocatalysis, photovoltaics, and neuromorphic computing. The unique functional properties of thi…
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…
