本项目拟基于线性量子引力理论研究低能量子引力效应。主要研究内容如下：1、从微扰论出发研究由线性化引力场的真空涨落和热涨落导致的两个可引力极化物体之间的单极--单极和单极--四极相互作用，得到它们对经典牛顿引力势的量子修正；2、研究有紧致化额外维时空和膜理论中两物体之间经典引力相互作用的量子修正，得到额外维对量子修正的影响；3、利用开放量子系统方法研究线性化引力场的真空涨落和热涨落对两物体纠缠动力学的影响。通过本项目的研究我们希望系统地了解两物体之间的引力量子效应，为理解引力的量子性质提供有价值的结果。

In this program we plan to carry out investigation in the quantum effects of low energy gravity basing on the linearized quantum gravity theory. The main contents inlude: 1. using leading-order perturbation theory to study the monopole--monopole and monopole--quadruple interactions between two gravitationally polarizable objects arising from vacuum fluctuations and thermal fluctuations of linearized gravitational field, and then obtain the quantum corrections on classical Newton potential of gravity；2. investigating the quantum corrections on classical gravity in the brane theory and the spacetime with compactified extra spatial dimensions, and discussing the effects of extra dimensions on quantum corrections; 3. using the open quantum system to study the entanglement dynamics between two massive objects interacting with the linearized gravitational fields in vacuum and thermal equilibrium. Thus, we hope to, in the present program, obtain systematically the effects of low energy quantum gravity on two gravitationally polarizable objects, which will provide valuable results on understanding the quantum propertie of gravity.
