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…

Dimensional reduction in quantum spin-1/2 system on a 1/7-depleted triangular lattice
Ryo Makuta, Chisa Hotta
We study the magnetism of a quantum spin-1/2 antiferromagnet on a maple-leaf lattice which is obtained by regularly depleting 1/7 of the sites of a triangular lattice. Although the…
