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…
Magnetic Dirac Fermions and Chern Insulator Supported on Pristine Silicon Surface
Huixia Fu, Zheng Liu, Chao Lian +4
Emergence of ferromagnetism in non-magnetic semiconductors is strongly desirable, especially in topological materials thanks to the possibility to achieve quantum anomalous Hall ef…
