Dr. Ji et al., DYNAMIC CRITICAL-BEHAVIOR OF 2D X-Y MODEL ON A RANDOM LATTICE FROM CLUSTER UPDATE MONTE-CARLO, Communications in Theoretical Physics, 20(4), 1993, pp. 477-480
We performed a numerical simulation of X-Y model on the two-dimensiona
l random lattice using cluster update algorithm. The critical region w
as found around beta approximate to 1.0 by the peaks in the specific h
eat and the susceptibility. The autocorrelation in energy and the squa
re of magnetization was also calculated. The results show that the cri
tical slowing down greatly reduced.
