Long-range order in the 2D antiferromagnetic Heisenberg model: A renormalization perspective

H. Q. Lin, David K Campbell

Applying a renormalization-group (RG) procedure to the 2D antiferromagnetic Heisenberg (AFH) model, we derive an effective AFH model in which spins on a 1D ring experience antiferromagnetic nearest-neighbor interactions and iteract individually with an effective central spin. Using analytic and numerical arguments, we establish the existence of staggered long-range order in the effective model and hence, given our RG prescription, in the 2D AFH. Our RG calculations give a value of the magnetic moment consistent with Monte Carlo results for the 2D AFH.

Snapshot Observation for 2D Classical Lattice Models by Corner Transfer Matrix Renormalization Group

Kouji Ueda, 両太 大谷, Yukinobu Nishio +2 more

We report a way of obtaining a spin configuration snapshot, which is one of the representative spin configurations in the canonical ensemble, inside a finite area of infinite size two-dimensional (2D) classical lattice models.The corner transfer matrix renormalization group (CTMRG), a variant of the density matrix renormalization group (DMRG), is used for the numerical calculation.The matrix product structure of the variational state in CTMRG makes it possible to stochastically fix spins each by each according to the conditional probability with respect to their environment.
