中子散射已成为在原子尺度上研究材料性质的关键技术。其独特性在于热中子的波长和能量分别与凝聚态物质中的原子间距和激发能量相当;因此,中子散射技术可直接用于研究材料的静态性质以及动力学性质。此外,中子有磁矩,在磁性研究方面具有独特的优势。《中子散射在凝聚态物理中的应用》介绍了中子散射的基本原理及相关实验仪器,讲述了凝聚态物理中重要的一些物理现象及材料性质,并以典型的中子散射实验为例,着重阐释了如何从实验测量中提取并分析相关的重要信息。
This book is a course in modern quantum field theory as seen through the eyes of a theoristworking in condensed matter physics. It contains a gentle introduction to the subject andcan therefore be used even by graduate students. The introductory parts include a deriva-tion of the path integral representation, Feynman diagrams and elements of the theory ofmetals including a discussion of Landau Fermi liquid theory. In later chapters the discus-sion gradually turns to more advanced methods used in the theory of strongly correlatedsystems. The book contains a thorough exposition of such nonperturbative techniques as1/N-expansion, bosonization (Abelian and non-Abelian), conformal field theory and theoryof integrable systems. The book is intended for graduate students, postdoctoral associatesand independent researchers working in condensed matter physics.
在长达两个多世纪的时间里,恐龙这地球存在56亿年来最壮丽的生命!带给我们许多迷惑和惊喜,也让人充分发挥了想象力。或许我们不会再有机会亲眼目睹这些史前动物了。我们能做的就是充分发挥想象力,从化石中搜寻出蛛丝马迹,并进行深度解密。《恐龙专家:肉食恐龙深度解密》以12开铜版纸四色印刷精美呈现了近八十种肉食恐龙的生存年代、体型特征、化石产地等信息。
Research on electronic systems in condensed matter physics is at present developing very rapidly, where the main focus is changing from the "single-particle problem" to the "many-particle problem". That is, the main research interest changed from phenomena that can be understood in the single particle picture, as, for example, in band theory, to phenomena that arise owing to the interaction between many electrons.
