Tight-binding theory of NMR shifts in topological insulators Bi2Se3 and Bi2Te3

Samuel Boutin, Jorge Ramírez-Ruiz, Ion Garate

Motivated by recent nuclear magnetic resonance (NMR) experiments, we present a microscopic sp3 tight-binding model calculation of the NMR shifts in bulk Bi2Se3, and Bi2Te3. We comp…
