Spin-chirality decoupling and critical properties of a two-dimensional fully frustrated XY model
Soichirou Okumura, Hajime Yoshino, Hikaru Kawamura
We study the ordering of the spin and the chirality in the fully frustrated XY model on a square lattice by extensive Monte Carlo simulations. Our results indicate unambiguously th…

Novel spin-liquid states in the frustrated Heisenberg antiferromagnet on the honeycomb lattice
Soichiro Okumura, Hikaru Kawamura, Tsuyoshi Okubo +1
Recent experiment on a honeycomb-lattice Heisenberg antiferromagnet (AF) BiMnO(NO) revealed a novel spin-liquid-like behavior down to low temperature, which was…
