Semiclassical theory of the magnetization process of the triangular lattice Heisenberg model
Tommaso Coletta, Tamás Tóth, Karlo Penc +1
Motivated by the numerous examples of 1/3 magnetization plateaux in the triangular lattice Heisenberg an- tiferromagnet with spins ranging from 1/2 to 5/2, we revisit the semiclass…
Competition between two- and three-sublattice ordering for S=1 spins on the square lattice
Tamas A. Toth, Andreas M. Laeuchli, Frederic Mila +1
We provide strong evidence that the S=1 bilinear-biquadratic Heisenberg model with nearest-neighbor interactions on the square lattice possesses an extended three-sublattice phase…
Three-sublattice ordering of the SU(3) Heisenberg model of three-flavor fermions on the square and cubic lattices
Tamas A. Toth, Andreas M. Laeuchli, Frederic Mila +1
Combining a semi-classical analysis with exact diagonalizations, we show that the ground state of the SU(3) Heisenberg model on the square lattice develops three-sublattice long-ra…
