Crossover from Spin-Density-Wave to Neel-like Ground state
arXiv:cond-mat/9410019 · doi:10.1103/PhysRevB.51.8310
Abstract
The characterization and evolution of a Spin Density Wave into the Quantum Neel ground state is considered in the context of a weak coupling theory of the half-filled Hubbard model. Magnetic properties obtained from this weak coupling approach in one dimension compare favorably with exact results from Bethe ansatz (BA). A study of the evolution of several length scales from weak to strong coupling is also presented.
