Bohmian力学的统一性和概率守恒的解
Uniqueness of Bohmian Mechanics, and Solutions From Probability Conservation
摘要：
我们证明了一维玻姆力学是唯一的，因为玻姆轨道是唯一的解决方案，保存总左（或右）的概率。在Brandt等人的研究中，Phys. Lett. A，249（1998）265- 270，它们定义了分位数运动--唯一的轨迹是通过假设粒子每一侧的总概率守恒来求解的。他们认为分位数轨迹与玻姆轨迹相同。然而，他们的论证没有注意到量子几率流定义中的规范自由。我们的论文回避了概率流的这种不确定性。如果波函数是可分的，则一维概率守恒可用于高维问题。几个例子给出了使用总左概率守恒，最值得注意的是，双缝实验。
英文摘要：
We show that one-dimensional Bohmian mechanics is unique, in that, the Bohm trajectories are the only solutions that conserve total left (or right) probability. In Brandt et al., Phys. Lett. A, 249 (1998) 265--270, they define quantile motion--unique trajectories are solved by assuming that the total probability on each side of the particle is conserved. They argue that the quantile trajectories are identical to the Bohm trajectories. Their argument, however, fails to notice the gauge freedom in the definition of the quantum probability current. Our paper sidesteps this under-determinedness of the probability current. The one-dimensional probability conservation can be used for higher dimensional problems if the wave function is separable. Several examples are given using total left probability conservation, most notably, the two-slit experiment.
