Phase transition in the transverse Ising model using the extended coupled-cluster method
J. Rosenfeld, N. E. Ligterink
The phase transition present in the linear-chain and square-lattice cases of the transverse Ising model is examined. The extended coupled cluster method (ECCM) can describe both si…

The Extended Coupled Cluster Treatment of Correlations in Quantum Magnets
J. Rosenfeld, N. E. Ligterink, R. F. Bishop
The spin-half XXZ model on the linear chain and the square lattice are examined with the extended coupled cluster method (ECCM) of quantum many-body theory. We are able to describe…
