A nonperturbative microscopic theory of Hamiltonian lattice gauge systems
R. F. Bishop, N. J. Davidson, Y. Xian
A review is given of our recent application of a systematic microscopic formulation of quantum many-body theory, namely the coupled-cluster method (CCM), to Hamiltonian latt…

Systematic Inclusion of High-Order Multi-Spin Correlations for the Spin- Models
R. F. Bishop, R. G. Hale, Y. Xian
We apply the microscopic coupled-cluster method (CCM) to the spin- models on both the one-dimensional chain and the two-dimensional square lattice. Based on a system…

Theory of Valence-Bond Lattice on Spin Lattice
Yang XIAN
Quantum spin-lattice systems in low dimensions exhibit a variety of interesting zero-temperature phases, some of which show non-classical (i.e., non-magnetic) long-range orders, su…
