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-…
