High-Order Coupled Cluster Calculations Via Parallel Processing: An Illustration For CaVO
D. J. J. Farnell, J. Schulenburg, J. Richter +1
The coupled cluster method (CCM) is a method of quantum many-body theory that may provide accurate results for the ground-state properties of lattice quantum spin systems even in t…

Phase Transition Of The Spin-One Square-Lattice Anisotropic Heisenberg Model
D. J. J. Farnell, K. A. Gernoth, R. F. Bishop
The coupled cluster method (CCM) is applied to the spin-one anisotropic Heisenberg antiferromagnet (HAF) on the square lattice at zero temperature using a new high-order CCM ground…
