平行回火蒙特卡罗自由能测量

Measuring free energy in parallel tempering Monte Carlo

Wenlong Wang

摘要:

本文讨论了用指数平均法测量平行回火Monte Carlo中绝对自由能的有效方法,并与用三维Edwards-AndersonIsing自旋玻璃模型作为基准测试的粒子数退火Monte Carlo结果进行了比较。数值结果表明,平行回火,即使使用的温度比人口退火少得多,但同样有效地测量绝对自由能模拟每个温度更长的时间。

英文摘要:

An efficient approach of measuring the absolute free energy in parallel tempering Monte Carlo using the exponential averaging method is discussed and the results are compared with those of population annealing Monte Carlo using the three-dimensional Edwards-Anderson Ising spin glass model as benchmark tests. Numerical results show that parallel tempering, even though uses a much less number of temperatures than population annealing, can nevertheless equally efficiently measure the absolute free energy by simulating each temperature for longer times.
