Spin wave dispersion in La2CuO4
arXiv:cond-mat/0201151 · doi:10.1103/PhysRevB.65.132404
Abstract
We calculate the antiferromagnetic spin wave dispersion in the half-filled Hubbard model for a two-dimensional square lattice and find it to be in excellent agreement with recent high-resolution inelastic neutron scattering performed on La2CuO4 [Phys. Rev. Lett. 86, 5377 (2001)].
