Effective spin model with anisotropic exchange interactions for the spin-orbit coupled Hubbard model at half-filling
Ryo Makuta, Chisa Hotta
Spin-orbit coupling (SOC) in noncentrosymmetric materials is the source of incommensurate magnetic structures. In semiconductors, it drives the Rashba spin splitting and spin momen…

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…
