利用路径积分求解引力场作用下中子干涉的相移

Solving the Interferometer Phase Shift of the Neutron in Gravitational Field by Path Integral Method

在分析引力场中中子干涉实验原理的基础上,通过等价变换,运用路径积分的方法分析两中子束在双缝实验中产生的相移,给出具体定量的相移公式。表述式虽与Staudenmann等人的分析不同,但物理意义一致,且所得结果简洁明了,物理图像清晰。

Based on the analysis of the experiment principle of the neutron interferometer in the gravitational field, the phase shift of two neutron beam in the double-slit experiment is studied through equivalent transformation by using path integral method. The obtained phase shift formula is different from that of Staudenmann et al. , but the physics meaning is consistent. Evenmore, the obtained formula is concise and give a more clear physics picture.
