量子力学中的谐振子:第三种方法

The Harmonic Oscillator in Quantum Mechanics: A Third Way

F. Marsiglio

摘要:

本科量子力学的课程通常集中在解决薛定谔方程的几个简单的一维例子。当引入希尔伯特空间的概念时,只使用了学术上的例子,例如狄拉克升降算符或角动量算符的矩阵表示。我们介绍了一些相同的一维矩阵对角化问题的例子,与一个基础,由无限的一组方井特征函数。本科生有能力在熟悉的环境中处理这些问题。我们特别注意一维谐振子。这篇论文应使学生掌握任何一维短程势的低束缚态。

英文摘要:

Courses on undergraduate quantum mechanics usually focus on solutions of the Schrödinger equation for several simple one-dimensional examples. When the notion of a Hilbert space is introduced only academic examples are used, such as the matrix representation of Dirac's raising and lowering operators or the angular momentum operators. We introduce some of the same one-dimensional examples as matrix diagonalization problems, with a basis that consists of the infinite set of square well eigenfunctions. Undergraduate students are well equipped to handle such problems in familiar contexts. We pay special attention to the one-dimensional harmonic oscillator. This paper should equip students to obtain the low lying bound states of any one-dimensional short range potential.
