"Filtering" CFTs at large N: Euclidean Wormholes, Closed Universes, and Black Hole Interiors
Hong Liu
Despite its successes, the large- holographic dictionary remains incomplete. Key features of gravitational path integrals--most notably Euclidean wormholes and the associated fa…
Probing Stringy Horizons with Pole-Skipping in Non-Maximal Chaotic Systems
Ping Gao, Hong Liu
In this paper, we study pole-skipping in non-maximally quantum chaotic systems. Using Rindler conformal field theories and the large- SYK chain as illustrative examples, we argu…
Lectures on entanglement, von Neumann algebras, and emergence of spacetime
Hong Liu
We review recent developments in the use of von Neumann algebras to analyze the entanglement structure of quantum gravity and the emergence of spacetime in the semi-classical limit…
Towards a holographic description of closed universes
Hong Liu
We study baby closed universes in AdS, focusing on the Antonini-Sasieta-Swingle (AS) cosmology, which arises in the gravitational description of partially entangled thermal sta…
The Making of von Neumann Algebras from Bulk Focusing
Netta Engelhardt, Hong Liu
The single-trace, infinite-N algebra of an arbitrary region may or may not be a von Neumann algebra depending on the GNS sector. In this paper we identify the holographic dual of t…
