标题： Lattice methods for students at a formal TASI

摘要： 这些关于格点场论的讲座是为TASI 2019，“量子场论的多个维度”而撰写的，并在该会议上进行了讲解。 参加这次TASI的学生大多对形式化的内容感兴趣，因此这些讲座略显不同：我想说明格点计算背后的物理动机，而不是描述所有的技术细节。 快速概要：(1) 宏观图景：格点基础，格点禁闭，摆脱格点。 (2) 格点计算各部分的概述——展示其中涉及的内容。 (3) 格点上的手征费米子。 （这部分可能对格点研究人员有兴趣。） (4) 案例研究：三维伊辛模型和QCD。 显示英文摘要

摘要： These lectures about lattice field theory were written for, and given at, TASI 2019, ``The many dimensions of quantum field theory.'' The students at this TASI were mostly interested in formal things, and so these are slightly unusual lattice lectures: I wanted to give the physical motivation behind lattice calculations rather than describe all the technical details. A quick outline: (1) The really big picture: lattice basics, lattice confinement, getting rid of the lattice. (2) A walk through the parts of a lattice calculation -- an overview, to show what's involved. (3) Chiral fermions on the lattice. (This part might be interesting to lattice people.) (4) Case studies: the three dimensional Ising model, and QCD.
