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 on the zero-temperature phase transition in the square lattice - 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 and (- model) at zero temperature…

High-Order Coupled Cluster Method (CCM) Calculations Via Parallel Processing: An Application To The Kagome Antiferromagnet
D. J. J. Farnell, R. F. Bishop
A simple ``brute-force'' parallelisation procedure for the computational implementation of high-order coupled cluster method (CCM) calculations is presented here. This approach is…
