High-order coupled cluster method calculations of spontaneous symmetry breaking in the spin-half one-dimensional J<sub>1</sub>-J<sub>2</sub> model
In this article we present new formalism for high-order coupled cluster method (CCM) calculations for "generalized" ground-state expectation values and the excited states of quantum magnetic systems with spin quantum number s ≥ 1/2. We use high-order CCM to demonstrate spontaneous symmetry...
