玻姆势的协变非局域相场模型

A covariant non-local phase field model of Bohm's potential

Roberto Mauri

摘要:

假设气体的能量非局部地依赖于其质量密度的对数,则所得到的运动方程中的体积力由密度梯度项之和组成。在第二项之后截断这个序列,得到玻姆的量子势和马德隆方程,明确地表明,导致量子力学公式b的一些假设确实承认基于非定域性的经典解释。在这里,我们推广这种方法施加一个有限的传播速度的任何扰动,从而确定一个协变公式的马德隆方程。

英文摘要:

Assuming that the energy of a gas depends non-locally on the logarithm of its mass density, the body force in the resulting equation of motion consists of the sum of density gradient terms. Truncating this series after the second term, Bohm's quantum potential and the Madelung equations are obtained, showing explicitly that some of the hypotheses that led to the formulationb of quantum mechanics do admit a classical interpretation based on non-locality. Here, we generalize this approach imposing a finite speed of propagation of any perturbation, thus determining a covariant formulation of the Madelung equation.
