Abstract

We analyze two old models of black holes to see whether they realize the AdS/CFT paradigm of ``multiple representations of bulk data by boundary states that differ only in the expectation value of exponentially complex operators" . We find that the explanation of the firewall paradox in these models is much simpler and corresponds to the naive way entanglement is resolved when small constituents escape from a complex chaotic quantum system. The real issue is that the quantum field theory (QFT) picture of the states near the boundary of a causal diamond is wrong. The phrase in quotes above is correct in our models because most of the states associated with any causal diamond cannot be associated with ANY states in quantum field theory.

The Origin and Fate of Rapid Negative Modes in Coleman--De Luccia Tunneling

Coleman--De Luccia tunneling can exhibit an infinite tower of rapidly oscillating negative modes, complicating the semiclassical evaluation of the path integral. We show that this tower does not represent infinitely many bounce-specific instabilities, but instead is tied to a single underlying gravitational conformal sector. This sector is exposed in two different ways: by a large scalar gradient near the bubble wall and by the turning point of a compact Euclidean geometry. The corresponding conformal sector is already present in fluctuations about the false vacuum. Treating the bounce and the false vacuum in the same well-defined gauge and with a common regulator, we find that their high-frequency negative spectra approach one another. The ultraviolet tower therefore cancels from the relative negative-mode count, leaving a single bounce-specific negative mode. This finite-backreaction spectral cancellation provides a corresponding picture of the result obtained in the small-backreaction limit.

Higher-form Symmetries of Linearized Gravity in Maximally Symmetric Spaces

We formulate the gravitational field on maximally symmetric spacetimes as a gauge theory, and investigate higher-form symmetries of the linearized gravitational field via a series expansion in Newton's gravitational constant. To treat gravity as a gauge theory, the MacDowell-Mansouri formulation based on Cartan geometry is utilized. We show the existence of a 1-form symmetry in linearized gravity on Minkowski spacetime. Furthermore, for other maximally symmetric spacetimes (de Sitter and anti-de Sitter spacetimes) with a small cosmological constant, we demonstrate the existence of an approximate 1-form symmetry in the corresponding linearized gravity, detailing its explicit dependence on the cosmological constant.

A Concise Course in String Theory

These lecture notes offer a concise introduction to string theory, based on a one-semester graduate course taught at Fudan University, and develop the subject from the string sigma model action to the AdS/CFT correspondence. The exposition is deliberately compact, and is addressed to graduate students who seek a coherent overview of the foundations of the subject rather than an exhaustive treatment.
