我们提出了一个可行的实验室干涉实验与物质波的引力势所造成的一对人工场产生的质量。它将证明这些质量的存在(以及对于运动的原子,时间膨胀)会引起相移,即使它不会引起任何经典力。相移与原子康普顿频率时钟的引力红移(或时间膨胀)产生的相移相同。与电磁学中的阿哈罗诺夫-玻姆效应类似,量子力学相位是引力势的函数,而不是经典力的函数。
We propose a feasible laboratory interferometry experiment with matter waves in a gravitational potential caused by a pair of artificial field-generating masses. It will demonstrate that the presence of these masses (and, for moving atoms, time dilation) induces a phase shift, even if it does not cause any classical force. The phase shift is identical to that produced by the gravitational redshift (or time dilation) of clocks ticking at the atom's Compton frequency. In analogy to the Aharonov-Bohm effect in electromagnetism, the quantum mechanical phase is a function of the gravitational potential and not the classical forces.
