论文摘要
重力下的运动通用性是量子颗粒的等效原理。在这里，我们研究了一个量子粒子从重力电位中散射的时间，并表明使用适当的Bohmian配方制定的散射时间是对等效原理违规的指标。波袋的散射时间足够独特，可以区分Bohmian和哥本哈根的解释。单能固定状态的散射时间在这里表达为对波哈姆时间的修改，这是对等效性原理的敏感探测器。我们得出量子散射时间，并系统地分析等价原则。我们讨论了测量违规所需的实验设置，并描述了量子理论（包括隧道时间）可能测量时间的含义。
Universality of motion under gravity, the equivalence principle, is violated for quantum particles. Here, we study time it takes for a quantum particle to scatter from the gravitational potential, and show that the scattering time, formulated here using the opportune Bohmian formulation, acts as an indicator of the equivalence principle violation. The scattering times of wavepackets are distinctive enough to distinguish between the Bohmian and Copenhagen interpretations. The scattering time of mono-energetic stationary states, formulated here as a modification of the Bohmian time by probability undercurrents, turns out to be a sensitive probe of the equivalence principle violation. We derive the quantum scattering times, and analyze equivalence principle violating terms systematically. We discuss the experimental setup needed for measuring the violation, and describe implications of a possible measurement for time in quantum theory, including the tunneling time.
