| contents | The periodic Anderson Hamiltonian of the bulk samarium hexaboride is investigated in this article assuming the presence of ferromagnetic impurities (FM). The problem of large on-site electron-electron repulsion is reformulated in terms of a holonomic constraint using slave-boson technique. The model analysis yields the effective mass of electron and the possibility of the quantum anomalous Hall phase with integer value of the Chern number. Upon using the Fu-Kane-Mele formalism, it is indicated that the surface Hamiltonian without FM may correspond to a strong topological insulator. |
