Topological invariants in interacting quantum spin Hall: a cluster perturbation theory approach

Using cluster perturbation theory we calculate Green's functions, quasi-particle energies and topological invariants for interacting electrons on a 2D honeycomb lattice, with intrinsic spin–orbit coupling and on-site e–e interaction. This allows us to define the parameter range (Hubbard U versus spi...
