P.2009-10-282009-10-2819910163-1829https://hdl.handle.net/2445/9844The short-range resonating-valence-bond (RVB) wave function with nearest-neighbor (NN) spin pairings only is investigated as a possible description for the Heisenberg model on a square-planar lattice. A type of long-range order associated to this RVB Ansatz is identified along with some qualitative consequences involving lattice distortions, excitations, and their coupling.4 p.application/pdfeng(c) The American Physical Society, 1991Propietats magnètiquesEstructura molecularEstructura atòmicaMagnetic propertiesMolecular structureAtomic structureResonating-valence-bond theory for the square-planar latticeinfo:eu-repo/semantics/article63460info:eu-repo/semantics/openAccess
