Program package for multicanonical simulations of U(1) lattice gauge theory
摘要：
我们用Fortran 77语言编写了一个程序，用于四维U（1）格点规范理论在其相变附近的多正则模拟.这包括程序和例程的规范模拟使用偏置大都会热浴更新和超松弛，通过王朗道递归的多规范权重的确定，和多规范模拟与固定权重补充超松弛扫描。测量的行动，波利雅科夫环和他们的一些结构因素。代码的许多功能超越了特定的应用，并预计将是有用的其他格点规范理论模型，以及在统计物理系统。
英文摘要：
We document our Fortran 77 code for multicanonical simulations of 4D U(1) lattice gauge theory in the neighborhood of its phase transition. This includes programs and routines for canonical simulations using biased Metropolis heatbath updating and overrelaxation, determination of multicanonical weights via a Wang-Landau recursion, and multicanonical simulations with fixed weights supplemented by overrelaxation sweeps. Measurements are performed for the action, Polyakov loops and some of their structure factors. Many features of the code transcend the particular application and are expected to be useful for other lattice gauge theory models as well as for systems in statistical physics.
