标题： Wave optics of quantum gravity for massive particles

摘要： 在闵可夫斯基时空背景下的量子引力效应被考虑。 即使缺乏完整的量子引力理论，仍可以对量子引力涨落对大质量粒子传播的影响做出一些具体的预测。 我们证明尽管引力势涨落不会产生粒子散射，但由于非定域效应，它们会导致物质波的退相干。 对于质量量级为普朗克质量的点状大质量粒子，这种效应是显著的。 然而，这种类型的退相干对于实际的有限大小粒子来说是无法测量的。 显示英文摘要

摘要： Effects of the quantum gravity under Minkowski space-time background are considered. It is shown that despite the absence of the complete theory of quantum gravity, some concrete predictions could be made for the influence of the quantum gravitational fluctuations on the propagation of the massive particles. We demonstrate that although the gravitational potential fluctuations do not produce particle scattering, they cause decoherence of the matter waves due to off-shell effects. For point-like massive particles of the Planck mass order, the effect is considerable. However, this type of decoherence is beyond the measurable possibility for the real particles of the finite size.
