Topological magnons in a kagome lattice spin system with $XXZ$ and Dzyaloshinskii-Moriya interactions

Ranjani Seshadri, Diptiman Sen

We study the phases of a spin system on the Kagome lattice with nearest-neighbor $XXZ$ interactions with anisotropy ratio $\Delta$ and Dzyaloshinsky-Moriya interactions with strength $D…
