Monte Carlo simulations of the three-dimensional XY spin glass focusing on the chiral and the spin order
Tomoyuki Obuchi, Hikaru Kawamura
The ordering of the three-dimensional isotropic {\it XY} spin glass with the nearest-neighbor random Gaussian coupling is studied by extensive Monte Carlo simulations. To investiga…
Ordering of the Heisenberg spin glass in four dimensions
Hikaru Kawamura, Shinichirou Nishikawa
Ordering of the Heisenberg spin glass in four dimensions (4D) with the nearest-neighbor Gaussian coupling is investigated by equilibrium Monte Carlo simulations, with particular at…
Spin and chiral orderings of the antiferromagnetic XY model on the triangular lattice and their critical properties
Tomoyuki Obuchi, Hikaru Kawamura
We study the antiferromagnetic {\it XY} model on a triangular lattice by extensive Monte Carlo simulations, focusing on its ordering and critical properties. Our result clearly sho…
Finite-temperature transition of the distorted kagome-lattice Heisenberg antiferromagnet
Hiroshi Masuda, Tsuyoshi Okubo, Hikaru Kawamura
Motivated by the recent experiment on kagome-lattice antiferromagnets, we study the zero-field ordering behavior of the antiferromagnetic classical Heisenberg model on a uniaxially…
