Classification of magnon thermal Hall systems based on U(1) to non-Abelian gauge fields
Masataka Kawano, Chisa Hotta
Magnon thermal Hall effect in insulating magnets is the manifestation of Berry curvature in magnon bands, which is formulated using the emergent gauge fields that act on magnons as…

Spin-orbit coupled Hubbard skyrmions
Ryo Makuta, Chisa Hotta
When the material phases exhibit topological quantum numbers, they host defects protected by the nontrivial topology. Magnetic skyrmions are such ``quantized" objects and although…
