经典和非相对论性量子力学中自发对称性破缺的简单模型
Simple models exhibiting spontaneous symmetry breakdown in classical and non-relativistic quantum mechanics
摘要：
首先，分析了自发对称性击穿的经典模型的性质。然后，一些教学的非相对论量子力学模型，也用来说明自发对称性击穿的优点和缺点进行了讨论。最后，一个简单的量子力学玩具模型（线上的旋量，与自旋相关的相互作用），表现出自发破缺的内部对称性。
英文摘要：
First, the properties of a classical model of spontaneous symmetry breakdown are analyzed. Then, the pros and cons of some pedagogical non-relativistic quantum-mechanical models, also used to illustrate spontaneous symmetry breakdown, are discussed. Finally, a simple quantum-mechanical toy model (a spinor on the line, with a spin-dependent interaction) is presented, that exhibits the spontaneous breaking of an internal symmetry.
