论文摘要
我们探索在线性量子引力的框架中，在其基础状态中三个非点状物体之间的非增添三体量子引力四极相互作用，发现这种相互作用表现出$ r_a^{ - 5} r_b^{-5} r_c^{ - 5} r_c^{ - 5} r_c^{-5} r的距离行为，而近距离的特征则是很小的。对象和$ r_A^{ - 5} r_b^{ - 5} r_c^{ - 5}（r_a+r_a+r_b+r_c）^{ - 1} $在远处的距离中，该距离大于特征过渡波长大于特征过渡长度，其中$r_ξ$中$r_ξ$表示两个对象之间的距离$ $ $ a $ a $ a $ a g（c）。与真空中的两个地基物体之间的添加量子重力相互作用相比，在近距离和远方方案中始终具有吸引力，根据这些物体的几何构型，三个基态物体之间的非添加相互作用可以具有吸引力或排斥。也就是说，可以通过改变物体的几何布置来操纵非辅助三体量子重力相互作用的有吸引力或排斥性能。
We explore the nonadditive three-body quantum gravitational quadrupole interaction among three nonpointlike objects in their ground states in the framework of linearized quantum gravity and find that the interaction exhibits a distance behavior of $r_A^{-5}r_B^{-5}r_C^{-5}$ in the near regime where the interobject distances are small compared with the characteristic transition wavelength of the objects, and $r_A^{-5}r_B^{-5}r_C^{-5}(r_A+r_B+r_C)^{-1}$ in the far regime where the distances are larger than the characteristic transition wavelength, where $r_ξ$ denotes the distance between any two objects except object $ξ\;(ξ=A,B,C)$. Compared to the additive quantum gravitational interaction between two ground-state objects in vacuum which is always attractive both in the near and far regimes, the nonadditive interaction among three ground-state objects can be either attractive or repulsive depending on the geometrical configuration of these objects. That is, in principle, the attractive or repulsive properties of the nonadditive three-body quantum gravitational interaction can be manipulated by changing the geometrical arrangement of the objects.
