Description

Full text: The Resonance Valence Bond (RVB) state was (incorrectly) suggested as the solution to the ground state of the Hubbard model on the square and isotropic triangular lattices. Recently deconfined spinons, a natural feature of an RVB state, have been observed by neutron scattering in the frustrated antiferromagnetic Cs2CuCI4. Exact diagonalisation shows that the RVB state strongly overlaps with the exact ground state for some frustrated Heisenberg models. We develop the RVB theory of the Heisenberg model on the anisotropic triangular lattice (appropriate for Cs2CuCI4) in a magnetic field and compare the results with the aforementioned neutron scattering experiments.
