内容简介
《场论、重正化群和临界现象(第3版)》被列为学习场论入门的核心教材,很少有教材能够做到如此恰到好处,详略得当,难易适中。将粒子物理学的场论方法和概念与临界现象和统计力学中的巧妙衔接起来。第一版已经被证明了是一本十分有用的教材,第二版又详细介绍了有限尺寸标度、一般性和多耦合常数的临界行为,这些都是物理学家做研究很有价值的工具。
  目次:第一部分(基本观点和技巧:临界现象理论中的相关概念和观点;函数积分有关的相变问题公式;量子场论中的函数积分;顶点函数和对称性破缺;圈数和分量数的扩张;重整化;重整化群和临界区域中的标度;临界指数的计算;(第二部分)导论;主标度之外;一般性综述;多耦合临界行为;交叉现象;二维附近的临界现象;(第三部分)非扰动和数值方法:实空间方法;有限尺寸标度;蒙特卡洛方法、数值场论。附录:程序案例。
  读者对象:物理专业高年级本科生、研究生和相关专业的科研人员。
