The DSUBm approximation scheme for the coupled cluster method and applications to quantum magnets
A new approximate scheme, DSUBm, is described for the coupled cluster method. We apply it to two wellstudied (spin-1/2 Heisenberg antiferromagnet) spin-lattice models, namely: the XXZ and the XY models on the square lattice in two dimensions. Results are obtained in each case for the ground-state...
