On the completeness of contraction map proof method for holographic entropy inequalities

Ning Bao, Keiichiro Furuya, Joydeep Naskar

The contraction map proof method is the commonly used method to prove holographic entropy inequalities. Existence of a contraction map corresponding to a holographic entropy inequa…

Non-invertible defects from the Conway SCFT to K3 sigma models I: general results

Roberta Angius, Stefano Giaccari, Sarah M. Harrison +1

We initiate the study of supersymmetry-preserving topological defect lines (TDLs) in the Conway moonshine module . We show that the tensor category of such defects,…

Ryu-Takayanagi Formula for Multi-Boundary Black Holes from 2D Large- CFT Ensemble

Ning Bao, Hao Geng, Yikun Jiang

We study a class of quantum states involving multiple entangled CFTs in AdS/CFT, associated with multi-boundary black hole geometries, and demonstrate that the Ryu-Takayana…

Black Hole Complementarity and ER/EPR

Ning Bao, Grant N. Remmen

We demonstrate that wormholes must be entangled regardless of asymptotic boundary conditions. Assuming black hole complementarity, we argue that traversable wormholes instantiate e…

Scattering of Quantum Particles in de Sitter Spacetime I: The Formalism

Tomasz R. Taylor, Bin Zhu

We develop a formalism for computing the scattering amplitudes in maximally symmetric de Sitter spacetime with compact spatial dimensions. We describe quantum states by using the r…

A framework for generalizing toric inequalities for holographic entanglement entropy

Ning Bao, Keiichiro Furuya, Joydeep Naskar

We conjecture a multi-parameter generalization of the toric inequalities of \cite{Czech:2023xed}. We then extend their proof methods for the generalized toric inequalities in two w…
