Magnetic order in a spin-1/2 interpolating kagome-square Heisenberg antiferromagnet
R. F. Bishop, P. H. Y. Li, D. J. J. Farnell +1
The coupled cluster method is applied to a spin-half model at zero temperature (), which interpolates between Heisenberg antiferromagnets (HAF's) on a kagome and a square latt…

Magnetic order on a frustrated spin-1/2 Heisenberg antiferromagnet on the Union Jack lattice
R. F. Bishop, P. H. Y. Li, D. J. J. Farnell +1
We use the coupled cluster method (CCM) to study the zero-temperature phase diagram of a 2D frustrated spin-half antiferromagnet, the so-called Union Jack model. It is defined on a…
