Holographic codes and bulk RG flows

Xi Dong, Donald Marolf, Pratik Rath

We consider the coarse-graining of holographic quantum error correcting codes under a generalized notion of bulk renormalization-group flow. In particular, we study the renormaliza…

Geometric Entropies and their Hamiltonian Flows

Xi Dong, Donald Marolf, Pratik Rath

In holographic theories, the Hubeny-Rangamani-Takayanagi (HRT) area operator plays a key role in our understanding of the emergence of semiclassical Einstein-Hilbert gravity. When…

Entanglement Negativity and Replica Symmetry Breaking in General Holographic States

Xi Dong, Jonah Kudler-Flam, Pratik Rath

The entanglement negativity is a useful measure of quantum entanglement in bipartite mixed states. In random tensor networks (RTNs), which are related to fixed-a…

Null states and time evolution in a toy model of black hole dynamics

Xi Dong, Maciej Kolanowski, Xiaoyi Liu +2

Spacetime wormholes can provide non-perturbative contributions to the gravitational path integral that make the actual number of states in a gravitational system much smaller…

A Modified Cosmic Brane Proposal for Holographic Renyi Entropy

Xi Dong, Jonah Kudler-Flam, Pratik Rath

We propose a new formula for computing holographic Renyi entropies in the presence of multiple extremal surfaces. Our proposal is based on computing the wave function in the basis…

Constrained HRT Surfaces and their Entropic Interpretation

Xi Dong, Donald Marolf, Pratik Rath

Consider two boundary subregions and that lie in a common boundary Cauchy surface, and consider also the associated HRT surface for . In that context, the constrai…
