Gap State in YbB12 and SmB6: Real Kondo Insulators
TL;DR: In this paper, the Coulomb interaction was used to explain the origin of gap states in YbB12 and SmB6 and showed that an electron created by the mixing with the 4f state, and the hole created in the conduction band to screen the 4 f hole, form a bound state in low-carrier density systems.
