Spin-wave spectrum in La2CuO4 -- double occupancy and competing interaction effects
arXiv:cond-mat/0205117 · doi:10.1103/PhysRevB.66.092402
Abstract
The recently observed spin-wave energy dispersion along the AF zone boundary in La2CuO4 is discussed in terms of double occupancy and competing interaction effects in the Hubbard model on a square lattice.
