The spin-1/2 J1-J2 Heisenberg antiferromagnet on the square lattice: Exact diagonalization for N=40 spins
J. Richter, J. Schulenburg
We present numerical exact results for the ground state and the low-lying excitations for the spin-1/2 J1-J2 Heisenberg antiferromagnet on finite square lattices of up to N=40 site…

High-Order Coupled Cluster Method Study of Frustrated and Unfrustrated Quantum Magnets in External Magnetic Fields
D. J. J. Farnell, R. Zinke, J. Richter +1
We apply the coupled cluster method (CCM) in order to study the ground-state properties of the (unfrustrated) square-lattice and (frustrated) triangular-lattice spin-half Heisenber…

The DSUB Approximation Scheme for the Coupled Cluster Method and Applications to Quantum Magnets
R. F. Bishop, P. H. Y. Li, J. Schulenburg
A new approximate scheme, DSUB, is described for the coupled cluster method. We then apply it to two well-studied (spin-1/2 Heisenberg antiferromagnet) spin-lattice models, name…
