Probing the Penetration Depth of Topological Surface States by Magnetic Impurity Scattering in V-doped SbTe
Yidi Wang, Zeyu Ma, Pengcheng Chen +11
Topological insulators host Dirac surface states (SS) protected by time-reversal symmetry. Inter-surface hybridization can gap the SS and give rise to the quantum spin Hall effect…

Angle-resolved photoemission intensity for multi-orbital bands: Complex interplay between the self-energy matrix and the optical matrix elements
Yau Chuen Yam, Mona Berciu, George A. Sawayzky
We use a simple one-dimensional two-band model with electron-phonon coupling to illustrate some of the complications that arise in multi-band systems when trying to extract a self-…
