Hp. Ying et F. Chen, AN UPDATING SCHEME FOR THE LOOP-CLUSTER ALGORITHM FOR THE ANISOTROPICHEISENBERG-ANTIFERROMAGNET, Physics letters. A, 208(4-6), 1995, pp. 356-360
A loop-cluster algorithm is proposed to overcome the critical slowing
down in simulations of the anisotropic Heisenbeg antiferromagnet, the
XYZ model. The primary features of the algorithm are presented, which
suggest that this quantum system may also be studied as a classical sp
in system using cluster updating techniques.
