关于薛定谔方程的奇异拉格朗日量

On singular Lagrangian underlying the Schrödinger equation

A. A. Deriglazov

摘要:

我们分析了薛定谔方程的哈密顿性质,并证明了它可以被认为是源于奇异拉格朗日作用量(在哈密顿公式中有两个第二类约束).它用来表明,任何解决方案的薛定谔方程与时间无关的潜力可以表示为形式$Ψ=(-\frac{\hbar^2}{2m}\triangle+V)ϕ+i\hbar\partial_tϕ$,其中实场$ϕ(t, x^i)$是一些解决方案的非奇异拉格朗日理论被指定如下。概率守恒是场$ϕ$的能量守恒定律。在将场引入形式主义之后,它的数学结构变得类似于电动力学的数学结构:实场$ϕ$变成了一种波函数的势。

英文摘要:

We analyze the properties that manifest Hamiltonian nature of the Schrödinger equation and show that it can be considered as originating from singular Lagrangian action (with two second class constraints presented in the Hamiltonian formulation). It is used to show that any solution to the Schrödinger equation with time independent potential can be presented in the form $Ψ=(-\frac{\hbar^2}{2m}\triangle+V)ϕ+i\hbar\partial_tϕ$, where the real field $ϕ(t, x^i)$ is some solution to nonsingular Lagrangian theory being specified below. Preservation of probability turns out to be the energy conservation law for the field $ϕ$. After introducing the field into the formalism, its mathematical structure becomes analogous to those of electrodynamics: the real field $ϕ$ turns out to be a kind of potential for a wave function.
