正方格上O($N$)圈模型的临界线

Critical Line of the O($N$) Loop Model on the Square Lattice

Antônio Márcio P. Silva, Adriaan M. J. Schakel, Giovani L. Vasconcelos

摘要:

本文提出了一种有效的算法来模拟任意$N>0$值的正方形格上的O(N)回路模型。该方案将蠕虫算法与一种新的数据结构相结合,以解决循环交叉问题和在每次Monte Carlo更新时计算循环数的必要性。利用这一方案,我们确定了$0<N\le 2$的正方格点上O($N$)模型的临界点线(及其它性质)。

英文摘要:

An efficient algorithm is presented to simulate the O(N) loop model on the square lattice for arbitrary values of $N>0$. The scheme combines the worm algorithm with a new data structure to resolve both the problem of loop crossings and the necessity of counting the number of loops at each Monte Carlo update. With the use of this scheme, the line of critical points (and other properties) of the O($N$) model on the square lattice for $0<N\le 2$ have been determined.
