Tunable Dirac-point resonance induced by a STM-coupled Anderson impurity on a topological insulator surface
The interaction effect between the surface states of a topological insulator (TI) and a STM-coupled Anderson impurity is studied by using equations of motion of the Green’s functions. Remarkably, we show that when a coupling between the Anderson impurity and the STM tip is included, the tunneling re...
