Relativistic Tight-Binding Model for Hexagonal Lattice: Application to Graphene
Rohin Sharma, Amit Shrestha, Masahiko Higuchi +2
A non-perturbative relativistic tight-binding (TB) approximation method applicable to crystalline material immersed in a magnetic field was developed in 2015. To apply this method…
