AdS3 axion wormholes as stable contributions to the Euclidean gravitational path integral
Andrew Loveridge, Hao-Yu Sun
Recent work has demonstrated that Euclidean Giddings-Strominger axion wormholes are stable in asymptotically flat 4D Minkowski spacetime, suggesting that they should, at least naiv…
Universal Bound on Effective Central Charge and Its Saturation
Andreas Karch, Yuya Kusuki, Hirosi Ooguri +2
The effective central charge (denoted by ) is a measure of entanglement through a conformal interface, while the transmission coefficient (encoded in the coefficien…
The Photon Sphere and Response Functions in Holography
Marcos Riojas, Hao-Yu Sun
In this letter, we show the Unruh temperature of the photon sphere for an AdS-Schwarzschild black hole can be determined holographically from the retarded Green's function and…
Universality of Effective Central Charge in Interface CFTs
Andreas Karch, Yuya Kusuki, Hirosi Ooguri +2
When an interface connects two CFTs, the entanglement entropy between the two CFTs is determined by a quantity called the effective central charge. The effective central charge doe…
Towards -finiteness: -deformed open string amplitude
Yuqi Li, Hao-Yu Sun
Revisiting the Coon amplitude, a deformation of the Veneziano amplitude with a logarithmic generalization of linear Regge trajectories, we scrutinize its potential origins in a wor…
The Photon Sphere and the AdS/CFT Correspondence
Marcos Riojas, Hao-Yu Sun
The AdS/CFT correspondence connects bulk fields to boundary operators characterized by source frequency and angular momentum . Here we explore their connec…
Imprints of phase transitions on Kasner singularities
Elena Caceres, Sanjit Shashi, Hao-Yu Sun
Under the AdS/CFT correspondence, asymptotically AdS geometries with backreaction can be viewed as CFT states subject to a renormalization group (RG) flow from an ultraviolet (UV)…
Spacetime Subsystem Symmetries
Saba Asif Baig, Jacques Distler, Andreas Karch +2
One characteristic feature of many fractonic lattice models, and a defining property of the exotic field theories developed to describe them, are subsystem symmetries including a c…
Constructing Carrollian Field Theories from Null Reduction
Bin Chen, Reiko Liu, Haowei Sun +1
In this paper, we propose a novel way to construct off-shell actions of -dimensional Carrollian field theories by considering the null-reduction of the Bargmann invariant action…
Double holography in string theory
Andreas Karch, Haoyu Sun, Christoph F. Uhlemann
We develop the notion of double holography in Type IIB string theory realizations of braneworld models. The Type IIB setups are based on the holographic duals of 4d BCFTs comprisin…

Stephen Ebert, Christian Ferko, Hao-Yu Sun +1
JT gravity has a first-order formulation as a two-dimensional BF theory, which can be viewed as the dimensional reduction of the Chern-Simons description of gravity. We consid…
Deformations of Supersymmetric Quantum Mechanics
Stephen Ebert, Christian Ferko, Hao-Yu Sun +1
We define a manifestly supersymmetric version of the deformation appropriate for a class of -dimensional theories with or $\mathcal{N} = 2…
The Hitchhiker's Guide to 4d Superconformal Field Theories
Mohammad Akhond, Guillermo Arias-Tamargo, Alessandro Mininno +4
Superconformal field theory with supersymmetry in four dimensional spacetime provides a prime playground to study strongly coupled phenomena in quantum field theory…
Dual D-Brane Actions in Nonrelativistic String Theory
Stephen Ebert, Hao-Yu Sun, Ziqi Yan
We study worldvolume actions for D-branes coupled to the worldvolume U(1) gauge field and Ramond-Ramond (RR) potentials in nonrelativistic string theory. This theory is a self-cont…
Universal relations for holographic interfaces
Andreas Karch, Zhu-Xi Luo, Hao-Yu Sun
We study the entanglement entropy in 1+1 dimensional conformal field theories in the presence of interfaces from a holographic perspective. Compared with the well-known case of bou…
An Information Paradox and Its Resolution in de Sitter Holography

We formulate a version of the information paradox in de Sitter spacetime and show that it is solved by the emergence of entanglement islands in the context of the DS/dS corresponde…
Holographic duality for Ising CFT with boundary
Andreas Karch, Zhu-Xi Luo, Hao-Yu Sun
We extend the holographic duality between 3d pure gravity and the 2d Ising CFT proposed in [Phys. Rev. D 85 (2012) 024032] to CFTs with boundaries. Besides the usual asymptotic bou…
Double-Janus Linear Sigma Models and Generalized Reciprocity for Gauss Sums
Ori J. Ganor, Hao-Yu Sun, Nesty R. Torres-Chicon
We study the supersymmetric partition function of a 2d linear -model whose target space is a torus with a complex structure that varies along one worldsheet direction and a Kähl…
Probing holography in -adic CFT
Stephen Ebert, Hao-Yu Sun, Meng-Yang Zhang
We holographically calculate the partition functions of certain types of isotropic sectors of the CFTs dual to Bruhat-Tits trees and -adic BTZ black holes. Along the way, we pro…
Establishing strongly-coupled 3D AdS quantum gravity with Ising dual using all-genus partition functions

We study 3D pure Einstein quantum gravity with negative cosmological constant, in the regime where the AdS radius is of the order of the Planck scale. Specifically, when the Br…
