Theory of clusterization in orbitally degenerate transition-metal compounds driven by lattice instabilities
Soshun Ozaki, Kota Mitsumoto, Chisa Hotta
We derive an effective orbital-lattice model with quantum degrees of freedom for transition-metal compounds, providing a microscopic understanding of cluster formation driven…

Effects of the three-dimensional interplanar coupling on the centrosymmetric skyrmion crystal formation in the frustrated stacked-triangular Heisenberg model
R. Osamura, K. Aoyama, K. Mitsumoto +1
Effects of the three-dimensional (3D) interplanar coupling on centrosymmetric skyrmion crystal (SkX) formation is investigated via extensive Monte Carlo simulations on the frustrat…

Diffusionless relaxation of half-skyrmion liquid, hexatic, and crystalline states in a chiral molecular crystal
Kyohei Takae, Kota Mitsumoto
Particles in a crowded environment exhibit slow anomalous diffusion, and their efficient manipulation is important in controlling transport phenomena in complex materials. Skyrmion…
