论文摘要
Schrodinger-Newton方程经常被研究为结合引力自相互作用的Schrodinger方程的非线性修饰。但是，尚无证据表明自然是否确实是这种行为。这项工作调查了一种实验测试引力自我交往的可能方法。通过通过数值求解通过双裂缝的粒子来求解schrodinger-newton方程来研究自我重力对大规模颗粒干扰的影响。结果表明，引力自我交互的存在对可以在物质波干涉测量实验中进行测试的干扰条纹宽度有影响。值得注意的是，这种方法可以区分引力自我交流和环境引起的反应，因为后者不影响边缘宽度。该结果还将提供一种测试是否需要根据普通量子力学的规模进行量化重力的方法。
The Schrodinger-Newton equation has frequently been studied as a nonlinear modification of the Schrodinger equation incorporating gravitational self-interaction. However, there is no evidence yet as to whether nature actually behaves this way. This work investigates a possible way to experimentally test gravitational self-interaction. The effect of self-gravity on interference of massive particles is studied by numerically solving the Schrodinger-Newton equation for a particle passing through a double-slit. The results show that the presence of gravitational self-interaction has an effect on the fringe width of the interference that can be tested in matter-wave interferometry experiments. Notably, this approach can distinguish between gravitational self-interaction and environment induced decoherence, as the latter does not affect the fringe width. This result will also provide a way to test if gravity requires to be quantized on the scale of ordinary quantum mechanics.
