| description | 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. |
