Peierls versus Holstein models for describing electron-phonon coupling in perovskites
Yau-Chuen Yam, Mirko M. Moeller, George A. Sawatzky +1
We use the Momentum Average approximation together with perturbative approaches, in the appropriate limits, to study the single polaron physics on a perovskite lattice inspired by…

Probing Image Potential States on Topological Semimetal Antimony Surface
Jian-Feng Ge, Haimei Zhang, Yang He +4
A point charge near the surface of a topological insulator (TI) with broken time-reversal symmetry is predicted to generate an image magnetic charge in addition to an image electri…

Unexpected Zero Bias Conductance Peak on the Topological Semimetal Sb(111) with a Broken Bilayer
Yau-Chuen Yam, Shiang Fang, Pengcheng Chen +9
The long-sought Majorana fermion is expected to manifest in a topological-superconductor heterostructure as a zero bias conductance peak (ZBCP). As one promising platform for such…
