Frustrated Heisenberg antiferromagnet on the honeycomb lattice with spin quantum number $s \geq 1$

P H Y Li, R F Bishop, C E Campbell

The ground-state (GS) phase diagram of the frustrated spin- $s$ $J_{1}$ -- $J_{2}$ -- $J_{3}$ Heisenberg antiferromagnet on the honeycomb lattice is studied using the coupled cluster me…

Frustrated Heisenberg antiferromagnet on the honeycomb lattice: Spin gap and low-energy parameters

R. F. Bishop, P. H. Y. Li, O. Götze +2

We use the coupled cluster method implemented to high orders of approximation to investigate the frustrated spin- $\frac{1}{2}$ $J_{1}$ -- $J_{2}$ -- $J_{3}$ antiferromagnet on the hone…

Quasiclassical magnetic order and its loss in a spin-1/2 Heisenberg antiferromagnet on a triangular lattice with competing bonds

Peggy H. Y. Li, Raymond F. Bishop, Charles E. Campbell

We use the coupled cluster method (CCM) to study the zero-temperature ground-state (GS) properties of a spin-1/2 $J_{1}$ -- $J_{2}$ Heisenberg antiferromagnet on a triangular lattice…

Highly frustrated spin-lattice models of magnetism and their quantum phase transitions: A microscopic treatment via the coupled cluster method

R. F. Bishop, P. H. Y. Li, C. E. Campbell

We outline how the coupled cluster method of microscopic quantum many-body theory can be utilized in practice to give highly accurate results for the ground-state properties of a w…

Phase diagram of a frustrated spin- $\frac{1}{2}$ $J_{1}$ -- $J_{2}$ $X X Z$ model on the honeycomb lattice

P. H. Y. Li, R. F. Bishop, C. E. Campbell

We study the zero-temperature ( $T = 0$ ) ground-state (GS) properties of a frustrated spin-half $J_{1}^{X X Z}$ -- $J_{2}^{X X Z}$ model on the honeycomb lattice with nearest-neighbor and n…
