量子引力的规范冗余使得定域算符的定义变得模糊不清，因为它们依赖于规范的选择或类似于威尔逊线附加的选择的“引力敷料”。最近的工作确定了确切的AdS 3原场固定到一个February man-Graham规范。在这里，我们扩展了这项工作，并定义了原场与一般的引力敷料。我们首先研究了在U（1）Chern-Simons规范理论下带电的体场作为说明性的热身，然后将结果推广到引力。作为一个应用，我们计算了一个引力环校正的背景下的黑洞microstate的体边界相关，然后验证此计算使用新适应的递归关系。在欧几里德视界上的分支点出现在半经典修正子的1/c修正中。
The gauge redundancy of quantum gravity makes the definition of local operators ambiguous, as they depend on the choice of gauge or on a ‘gravitational dressing’ analogous to a choice of Wilson line attachments. Recent work identified exact AdS3 proto-fields by fixing to a Fefferman-Graham gauge. Here we extend that work and define proto-fields with general gravitational dressing. We first study bulk fields charged under a U(1) Chern-Simons gauge theory as an illustrative warm-up, and then generalize the results to gravity. As an application, we compute a gravitational loop correction to the bulk-boundary correlator in the background of a black hole microstate, and then verify this calculation using a newly adapted recursion relation. Branch points at the Euclidean horizon are present in the 1/c corrections to semiclassical correlators.
