摘要
本文首次在非对称点阵(ξ>1)上模拟了SU(2)纯规范场系统的热力学量,并讨论了有限大小效应和实现连续物理极限问题.结果表明:利用非对称点阵易于模拟格点规范场的热力学行为,也易于讨论趋向连续物理的各种极限.本文还把纠偏抽样技巧用于格点规范场的Monte-Carlo模拟,不但提高了计算效率,还能更好地计算热容C_v的温度行为.
The thermodynamical quantities of SU(2) pure lattice gauge field have been simulated first time on the asymmetric lattice (ξ>1). The finite size effect and continuum physics limits have also been studied. The results show that the use of asymmetric lattice is of benefit to calculate the thermodynamical quantities and study the behavior of continuum physics limits. In addition, it is explained that the efficiency of the whole Monte Carlo simulation and the calculation of heat capacity will be improved quite a lot by using bias sampling technique.
