Effect of anisotropy on the ground-state magnetic ordering of the spin-half quantum $J_{1}^{X X Z}$ -- $J_{2}^{X X Z}$ model on the square lattice

R. F. Bishop, P. H. Y. Li, R. Darradi +2

We study the zero-temperature phase diagram of the 2D quantum $J_{1}^{X X Z}$ -- $J_{2}^{X X Z}$ spin-1/2 anisotropic Heisenberg model on the square lattice. In particular, the effects o…

Coupled Cluster Treatment of the Shastry-Sutherland Antiferromagnet

R. Darradi, J. Richter, D. J. J. Farnell

We consider the zero-temperature properties of the spin-half two-dimensional Shastry-Sutherland antiferromagnet by using a high-order coupled cluster method (CCM) treatment. We fin…

Influence of the spin quantum number $s$ on the zero-temperature phase transition in the square lattice $J$ - $J^{'}$ model

R. Darradi, J. Richter, D. J. J. Farnell

We investigate the phase diagram of the Heisenberg antiferromagnet on the square lattice with two different nearest-neighbor bonds $J$ and $J^{'}$ ( $J$ - $J^{'}$ model) at zero temperature…
