从经典力学和普朗克假设推导薛定谔方程
Straightforward Derivation of the Schr{ö}dinger Equation from Classical Mechanics and the Planck Postulate
摘要:
根据广泛接受的概念,薛定谔方程(SE)原则上是不可导的。与这种信念相反,我们在这里提出了一个简单的推导SE。它仅基于两个力学基础:经典的哈密顿-雅可比方程(HJE)和关于微观尺度能量离散转移的普朗克假设。我们的方法是从其他出版的衍生SE,要么采用一个特设的基本假设的概率或统计性质的微观现象,或依赖于先验知识的SE,并通过引入一个新的假设来达到它-既不存在于经典力学,也不遵循实验-与一个合适的,但物理上不合理的选择一个关键的任意常数。
英文摘要:
According to the widely accepted notion, the Schr{ö}dinger equation (SE) is not derivable in principle. Contrary to this belief, we present here a straightforward derivation of SE. It is based on only two fundamentals of mechanics: the classical Hamilton-Jacobi equation(HJE) and the Planck postulate about the discrete transfer of energy at micro-scales. Our approach is drastically different from the other published derivations of SE which either employ an ad hoc underlying assumption about the probabilistic or the statistical nature of the micro-scale phenomena, or rely on the prior knowledge of SE and arrive at it by introducing a new postulate - neither present in classical mechanics nor following from experiments - with a suitable but physically unjustifiable choice of a key arbitrary constant.
