Topological phases of higher Chern numbers in Kitaev-Heisenberg ferromagnet with further-neighbor interactions

Moumita Deb, Asim Kumar Ghosh

Emergence of multiple topological phases with a series of Chern numbers, $\pm 1$ , $\mp 1$ , $\pm 2$ , $\mp 2$ , $\pm 3$ and $\mp 4$ , are observed in a ferromagnetic Kitaev-Heisenberg-…

Non-trivial Topological Phases on the Stuffed Honeycomb Lattice

Arghya Sil, Asim Kumar Ghosh

We report the appearance of nontrivial topological phases in a tight-binding model on the stuffed honeycomb lattice. The model contains nearest neighbor and next nearest neighbor h…
