刘维尔方程与薛定谔方程的联系

On the conection between the Liouville equation and the Schrodinger equation

Edelver Carnovali, Humberto M. Franca

摘要:

从相空间中的经典Liouville方程出发,导出了一个经典的Schrodinger型方程。推导是基于经典的相空间概率分布,这取决于一个任意常数$α$与行动的维度的维格纳型傅里叶变换。为了实现这一目标,需要满足两个条件:1)假设经典概率幅$Ψ(x,t)$可以展开为位形空间中定义的一组完备函数$Φ_n(x)$; 2)经典相空间分布$W(x,p,t)$服从Liouville方程,并且是位置、动量和时间的实函数。我们表明,常数$α$出现在经典的相空间分布的傅里叶变换,也在经典的薛定谔型方程,有它的起源在真空零点辐射的光谱分布,并确定与普朗克常数$\hbar$。

英文摘要:

We derive a classical Schrodinger type equation from the classical Liouville equation in phase space. The derivation is based on a Wigner type Fourier transform of the classical phase space probability distribution, which depends on an arbitrary constant $α$ with dimension of action. In order to achieve this goal two requirements are necessary: 1) It is assumed that the classical probability amplitude $Ψ(x,t)$ can be expanded in a complete set of functions $Φ_n(x)$ defined in the configuration space; 2) the classical phase space distribution $W(x,p,t)$ obeys the Liouville equation and is a real function of the position, the momentum and the time. We show that the constant $α$ appearing in the Fourier transform of the classical phase space distribution, and also in the classical Schrodinger type equation, has its origin in the spectral distribution of the vacuum zero-point radiation, and is identified with the Planck's constant $\hbar$.
