Spin-Wave Theory for the Scalar Chiral Phase in the Multiple-Spin Exchange Model on a Triangular Lattice
Shogo Taira, Chitoshi Yasuda, Tsutomu Momoi +1
We study the effects of quantum fluctuations on a non-coplanar tetrahedral spin structure, which has a scalar chiral order, in the spin-1/2 multiple-spin exchange model with up to…
Ground-State Phase Diagram of the Multiple-Spin Exchange Model with up to the Six-Spin Exchange Interactions on the Triangular Lattice
Chitoshi Yasuda, Yuma Uchihira, Shogo Taira +1
The ground state of the multiple-spin exchange model with up to the six-spin exchange interactions on a triangular lattice in the magnetic field is investigated within the mean-fie…
Spin nematic order in multiple-spin exchange models on the triangular lattice
Tsutomu Momoi, Philippe Sindzingre, Kenn Kubo
We figure out that the ground state of a multiple-spin exchange model applicable to thin films of solid 3He possesses an octahedral spin nematic order. In the presence of magnetic…
Vortex generation in the RSP game on the triangular lattice
Hiroyuki Nishiuchi, Naomichi Hatano, Kenn Kubo
A new model of population dynamics on lattices is proposed. The model consists of players on lattice points, each of which plays the RSP game with neighboring players. Each player…
Phase Diagram of Spinless Fermions on an Anisotropic Triangular Lattice at Half-filling
Chisa Hotta, Nobuo Furukawa, Akihiko Nakagawa +1
The strong coupling phase diagram of the spinless fermions on the anisotropic triangular lattice at half-filling is presented. The geometry of inter-site Coulomb interactions rules…
Spin-Wave Theory of the Multiple-Spin Exchange Model on a Triangular Lattice in a Magnetic Field : 3-Sublattice Structures
Chitoshi Yasuda, Daisuke Kinouchi, Kenn Kubo
We study the spin wave in the S=1/2 multiple-spin exchange model on a triangular lattice in a magnetic field within the linear spin-wave theory. We take only two-, three- and four-…
