Antiferromagnetic Potts models on the square lattice.
We study the antiferromagnetic q-state Potts model on the square lattice for q = 3 and q = 4, using the Wang-Swendsen-Koteck y Monte Carlo algorithm and a new nite-size-scaling extrapolation method. For q = 3 we obtain good control up to correlation length 5000; the data are consistent with () = Ae 2 (1 + a 1 e +. . .) as ! 1. For q = 4 the model is disordered even at zero temperature.
متن کاملDestruction of long-range antiferromagnetic order by hole doping
We study the renormalization of the staggered magnetization of a twodimensional antiferromagnet as a function of hole doping, in the framework of the t-J model. It is shown that the motion of holes generates decay of spin waves into ”particle-hole” pairs, which causes the destruction of the long-range magnetic order at a small hole concentration. This effect is mainly determined by the coherent...
متن کامل1/N expansion and long range antiferromagnetic order.
The staggered magnetization of the Heisenberg antiferromagnet in two dimensions can be systematically approximated by a 1/N expansion. Cancellation between self energy diagrams leads to a Luttingerlike theorem for the ground state. We prove (for a smooth enough self energy) that the long range order of mean field theory (N=∞) survives corrections to all orders of 1/N . Divergences of this serie...
متن کاملIsing models with long-range antiferromagnetic and short-range ferromagnetic interactions
We study the ground state of a d–dimensional Ising model with both long range (dipole–like) and nearest neighbor ferromagnetic (FM) interactions. The long range interaction is equal to r−p, p > d, while the FM interaction has strength J . If p > d+1 and J is large enough the ground state is FM, while if d < p ≤ d + 1 the FM state is not the ground state for any choice of J . In d = 1 we show th...
