量子物理

前言

The first edition of Quantum Physics was published about thirty years ago. The guide-lines that i set out in the preface to that edition as well as its general approach are ones towhich I still subscribe. I wrote:This book is intended to serve as an introduction to quantum physics. In writing it, Ihave kept several guidelines in mind:1. First, it is helpful for the development of intuition in any new field of study to start with a base of detailed knowledge about simple systems. I have therefore worked out a number of problems in great detail, so that the insight thus obtained can be used for more complex systems.2. Every aspect of quantum mechanics has been helpful in understanding some physical phenomenon. I have laid great stress on applications at every stage of development of the subject. Although no area of quantum mechanics is totally developed,my intention is to bridge the gap between a modem physics course and the moreformal development of quantum mechanics. Thus, many applications are discussed,and I have stressed order-of-magnitude estimates and the importance of numbers.3. In keeping with the level of the book, the mathematical structure has been kept assimple as possible. New concepts, such as operators, and new mathematical toolsnecessarily make their appearance. I have dealt with the former more by analogy thanby precise definition, and I have minimized the use of new tools insofar as possible. There were few changes in the second edition. This, the third edition, is not funda-mentally different in spirit from the first two, but it differs in detail in many ways.The principal changes are the following:（a） The ordering of chapters has been changed. This edition of the book divides more neatly into the basics of quantum mechanics and the most important applications that one would want to cover in a one-semester course versus a series of chapters on more general applications. Because I have tended to build new mate rial on the base of previously discussed material, this change makes the book more useful for a one-semester course.（b） In response to advice from a number of users of the book, I have expanded somewhat the discussion of the general structure of wave mechanics and the more abstract description of quantum mechanics （including the Dirac notation）. In keeping with guideline 3 listed above, I have avoided the introduction of a mini-course on linear algebra. This beautiful mathematical development is best treated in a first year graduate course.（c） I did not wish to increase the size of the book and have therefore shortened parts of the text by putting some material on the book's web site [wwW.wiloy.con/college/ gasiorowicz. This material consists of several kinds of supplements:some longer derivations or arguments that are not central to the developmentof a particular subject; examples include the discussion of the derivation of theblackbody radiation formula, as derived by Einstein, and topics in the additionof angular momentum.
