内容简介
本书是量子力学的世界经典教材,内容丰富,结构严谨,逻辑性强。作者从所需的数学基础开始,先复习经典力学,再通过一些实验事实说明经典物理学遇到的困难和引入量子理论的必要性,然后详细阐述量子力学的基本原理及其进一步发展,给出实际问题的具体解决方法和处理过程。本书叙述简明易懂,数学推导和例题分析详细,并附有大量的习题及其答案,是学习量子力学的理想教材。
在第2版中,作者做了全面的修订和补充,例如重写了数学基础部分,讨论了时间反演不变性,并多加了讨论路径积分的一个新章节(第21章:Path Integrals—II)。新版的亮点有:(1)量子力学的数学基础部分更加清晰明了;(2)充分回顾牛顿力学、拉格朗日力学和哈密顿力学,从而帮助学习者更好地理解量子力学与经典力学的不同之处;(3)通过数学定理和物理假设的分开处理加深读者对量子理论的理解;(4)深入讨论路径积分及其在现代物理学中的重要性。

“An excellent text … The postulates of quantum mechanics and the mathematical underpinnings are discussed in a clear, succinct manner.”
— American Scientist
“No matter how gently one introduces students to the concept of Dirac’s bras and kets, many are turned off. Shankar attacks the problem head-on in the first chapter, and in a very informal style suggests that there is nothing to be frightened of.”
— Physics Bulletin
“This massive text of 700 and odd pages has indeed an excellent get-up, is very verbal and expressive, and has extensively worked out calculational details—all just right for a first course. The style is conversational, more like a corridor talk or lecture notes, though arranged as a text. … It would be particularly useful to beginning students and those in allied areas like quantum chemistry.”
— Mathematical Reviews
