章节摘录

版权页:插图:You have captured the basic concepts and solved, as main applications, several quantum mechanical problems exactly inprevious chapters. However, it happens often that an interesting and important physical problem is described by a Schrsdinger equation that can not be solved exactly. It is therefore inevitable to develop various skills (strategies or methods). An important and powerful method is called perturbation theory that refers to any situation in which a solution to an equation is analyzed by using an existing nearby solution as a reference, or even possibly by solving a nearby equation rather than the original equation. In order for perturbation theory to be applicable, one or more of the following items should be true: (i) The desired initial data should be close to the reference initial data.  (ii) The desired equation should be close to the reference equation. (iii) The time interval on which the analysis is performed should be small. In this chapter you are guided to learn a very useful method: time-independent perturbation theory for bound states.

作者简介

《量子力学简明教程(英文)》内容简介:This is based on the author's following two principles: (i) if a textbook were so perfectly arranged that leaves nothing to be desired, it would make the readers feel that the scientific discovery is so mystical that they lose passion of creativity; (ii) if a course were so purely presented that highes on a perfect axiomatics without mention of incomplete doctrine in history of science, it would lose the chance of training students' power of creativity. College students should cultivate their ability of capturing knowledge and attain the power of employing knowledge in addition to the simple task of absorbing knowl-edge. So the author tried to adopt second-person pronoun in presenting this course. According to the author's teaching experience, some mediate steps of mathematical formulation that beginners are not able to figure out frequently, are also given. In order to avoid too much content in class, some important examples are arranged as problems with solutions.

  •     还可以,就是看起来有点旧,有点灰
  •     书收到了,帮别人买的,速度还算快吧
  •     Too many math, too little physics, but anyway it's clear and not very difficult to understand.
  •     呵呵,呵呵,呵呵,呵呵,呵呵,呵呵,呵呵,呵呵,呵呵,呵呵,呵呵,呵呵。
  •     简直是糟糕。唯一的优点是简略,但是一点也不简明啊。好多问题并没有说清楚,需要参考别的书才能懂。
