Emergent chiral symmetry in non-bipartite kagome and pyrochlore lattices with spin-orbit coupling
Hiroki Nakai, Masataka Kawano, Chisa Hotta
Chiral symmetry in energy bands appears as perfectly symmetric anti-bonding and bonding pairs of energy levels. It has only been observed in a few classes of models with a bipartit…

Phase diagram of the square lattice Hubbard model with Rashba-type antisymmetric spin-orbit coupling
Masataka Kawano, Chisa Hotta
We clarify the ground state phase diagram of the half-filled square-lattice Hubbard model with Rashba spin-orbit coupling (SOC) characterized by the spin-split energy bands due to…
