Development of Gauge Theory Numerical Experimental Tool

规范理论描述了基本粒子的相互作用，也是固体物理的有用技术。对于规范理论的分析，数值模拟是非常有力的研究方法。然而，由于计算机及相关技术的快速发展，对于那些不是数值分析专家的人来说，现在使用起来并不容易。在这个项目中，我们开发了一个环境，研究人员可以在其中使用规范理论模拟。为此，整个代码并不是一个黑匣子。它不是一套库，而是一套工具，研究人员可以用它来构建自己的程序。到目前为止，这个代码(晶格工具包)在日本国内外都在使用。我们尊重用户的意见，并对代码进行改进。

Gauge theories describe the interaction of fundamental particles, and it is also useful technique for the solid state physics. For the analysis of the gauge theories, numerical simulations are very powerful research method. However, due to the rapid progress in computers and related technique, it is now not so easy to employ for those who are not an expert of the numerical analysis. In this project, we have developed the environment in which researchers can use the gauge theory simulations. For this purpose, the whole code is not a black-box. It is not a set of libraries, but a set of tools with which researchers can construct their own program. So far this code (Lattice Tool Kit) is used in and out of Japan. We appreciate user's opinions and improve the code.
