Topological crystalline insulators and Dirac octets in antiperovskites
We predict a class of topological crystalline insulators in the antiperovskite material family with the chemical formula A[subscript 3]BX. Here the nontrivial topology arises from band inversion between two J = 3/2 quartets, which is described by a generalized Dirac equation for a "Dirac octet....
