Abstract:We have investigated the quantum J1-J2-J3 model on the honeycomb lattice with exact diagonalizations and linear spin-wave calculations for selected values of J2/J1, J3/J1 and antiferromagnetic (J1 > 0) or ferromagnetic (J1 < 0) nearest neighbor interactions. We found a variety of quantum effects: “order by disorder" selection of a Néel ordered ground-state, good candidates for non-classical ground-states with dimer long range order or spin-liquid like. The purely antiferromagnetic… CONTINUE READING
