在本文中，我们将首次研究自引力介观系统的波包如何在爱因斯坦广义相对论之外的理论中传播。特别地，我们将考虑一个没有鬼的无穷导数引力，它解决了势中的1 / r奇点-使得势的梯度在非定域尺度内消失。我们将证明，与牛顿的情况相比，无幽灵和无奇性引力的量子波包传播得更快，因此为我们在实验室中测试短距离引力的经典和量子性质提供了一个独特的场景在不久的将来。
In this paper we will study for the first time how the wave-packet of a self-gravitating meso-scopic system spreads in theories beyond Einstein’s general relativity. In particular, we will consider a ghost-free infinite derivative gravity, which resolves the 1 / r singularity in the potential – such that the gradient of the potential vanishes within the scale of non-locality. We will show that a quantum wave-packet spreads faster for a ghost-free and singularity-free gravity as compared to the Newtonian case, therefore providing us a unique scenario for testing classical and quantum properties of short-distance gravity in a laboratory in the near future.
