Description:
Author(s): F. Michaud and F. Mila We study the spin S =1 antiferromagnetic Heisenberg model on the square lattice with, in addition to the nearest-neighbor interaction, a three-site interaction of the form ( S i · S j )( S j · S k )+H.c. This interaction appears naturally in a strong coupling expansion of the two-orbital, half-filled Hubbard mod... [Phys. Rev. B 88, 094435] Published Thu Sep 26, 2013
