We explore the relationship between the quantum state of a compact matter source and of its asymptotic graviton field. For a matter source in an energy eigenstate, the graviton state is determined at leading order by the energy eigenvalue. Insofar as there are no accidental energy degeneracies there is a one to one map between graviton states on the boundary of spacetime and the matter source states. Effective field theory allows us to compute a purely quantum gravitational effect which causes the subleading asymptotic behavior of the graviton state to depend on the internal structure of the source. This establishes the existence of ubiquitous quantum hair due to gravitational effects.
我们探讨了致密物质源的量子态与其渐近引力子场之间的关系。对于处于能量本征态的物质源，引力子态在主导阶由能量本征值确定。只要不存在偶然的能量简并，时空边界上的引力子态与物质源态之间就存在一一对应关系。有效场论使我们能够计算一种纯粹的量子引力效应，该效应导致引力子态的次主导渐近行为取决于源的内部结构。这确立了由于引力效应而普遍存在的量子毛发的存在。
