- 요약This thesis reports on several aspects of semiclassical quantum gravity within the framework of holography duality. Among these are the relation between boundary causality and locality in AdS/CFT, correlation functions in 3d gravity and 2d CFT, and spin-refined observables computed by the gravitational path integral. Chapter 1 is introductory and describes some general features of semiclassical quantum gravity, holographic duality, and universal aspects of AdS3/CFT2. Following this introduction, Chapter 2 develops the machinery of 2d CFT more thoroughly. Chapter 3 studies an apparent paradox in AdS/CFT whereby the boundary subregion encoding a bulk point can appear to violate causality by moving superluminally. The paradox is resolved by the non-local nature of the encoding, which gives the boundary subregion its finite extent. The encoding region cannot jump outside of its domain of dependence, and therefore remains in causal contact with itself as it moves.Chapters 4 and 5 are concerned with holographic correlators in AdS3/CFT2. We consider fields propagating in the geometries of heavy objects like conical defects and BTZ black holes, which have dual descriptions as excited or thermal states of the CFT. These chapters describe several calculations of correlators of such fields using both gravity and CFT techniques. The match between the bulk and boundary results allows us to extract universal CFT data that determines the amplitudes to create excitations of the light field, as well as the expectation values of an infinite family of two-particle states exchanged between the heavy and light fields. In the CFT, these are HHL OPE coefficients for a family of double-trace operators whose presence is required by crossing symmetry.Chapter 6 investigates spin-refined partition functions in AdS/CFT using the Euclidean gravitational path integral. These objects have the form Tr (e −βHX), where X is a discrete isometry. We construct phase diagrams for various choices of X, devoting particular attention to the case where X is a reflection. A CRT -twisted black hole universally dominates the canonical ensemble for this quantity at high temperatures, while complex rotating black holes dominate the microcanonical ensemble at high energies.
