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…
Symmetry-protected topological polarons
Kaifa Luo, Jon Lafuente-Bartolome, Feliciano Giustino
Emergent quasiparticles in solids often exhibit unique topological properties as a result of the complex interplay between charge, orbital, spin and lattice degrees of freedom. Amo…
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…
