Continuing past the inner horizon using WKB
Features of the black hole interior can be extracted from the analytic structure of boundary correlation functions. Working in the geodesic approximation, we find analytic continuations that probe…

On the temperature of the quantum black hole
A nontrivial peculiarity of general relativity is that when the horizon region of black holes is rendered harmless, the exterior doubles, resulting in a causally disconnected parallel universe. This…

More on Pre-Inflationary Non Gaussianities
I generalize the three-point amplitude of curvature perturbations in the climbing scenario inspired by ten-dimensional non-supersymmetric strings to a broader class of exponential potentials, under…

Entanglement Viscosity: from Unitarity to Irreversibility in Accelerated Frames
We demonstrate that the unitarity of quantum field theory, through the positivity of spectral functions, underlies thermodynamic irreversibility for a subsystem separated by a horizon, in direct…

Wilson-'t Hooft classification and the perimeter law for dyonic loops in 3d monopole semiclassics
We investigate the long-distance behavior of dyonic loop operators in 4d SU(N) gauge theories on R3 × S1 using the 3d monopole semiclassics. If we employ the naive definition of…

Critical Phenomena on the Bethe Lattice
We investigate the critical behavior of a family of Z2-symmetric scalar field theories on the Bethe lattice (the tree limit of regular hyperbolic tessellations) using both the…

Quark confinement due to unified magnetic monopoles and vortices reduced from symmetric instantons with holography
We develop a geometric framework to analyze quark confinement in four-dimensional Euclidean SU(2) Yang--Mills theory in terms of finite-action topological defects. Starting from self-dual…

Tripartite Correlation Signal from Multipartite Entanglement of Purification
We propose a signal Δ(3)p for genuine tripartite entanglement in finite-dimensional quantum systems and Δ(3)w for holographic systems. We prove that Δ(3)p is non-negative for any…

More About the Spontaneous Breaking of Time Reversal in de Sitter Space
It is widely thought that the quantum theory of de Sitter space requires the existence of a physical observer in the static patch. What exactly is meant by an observer is unclear; it could be…

Tori, Klein Bottles, and Modulo 8 Parity/Time-reversal Anomalies of 2+1d Staggered Fermions
We study the symmetries of lattice staggered fermions in 2+1d. Using the symmetries, we can place the system on any sheared torus or Klein bottle. These different backgrounds provide diagnostics of…
