Modular flow and the area operator
Xi Dong, Donald Marolf, Pratik Rath
In the context of the AdS/CFT correspondence, the Jafferis-Lewkowycz-Maldacena-Suh (JLMS) formula relates the boundary modular Hamiltonian to the HRT area operator and the correspo…
The JLMS formula in a large code with approximate error correction
Xi Dong, Donald Marolf, Pratik Rath
Gauge/gravity duality is often described as a quantum error correcting code. However, as seen in the Jafferis-Lewkowycz-Maldacena-Suh (JLMS) formula, exact quantum error correction…
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…
Hollow-grams: Generalized Entanglement Wedges from the Gravitational Path Integral
Sami Kaya, Pratik Rath, Kyle Ritchie
Recently, Bousso and Penington (BP) made a proposal for the entanglement wedge associated to a gravitating bulk region. In this paper, we derive this proposal in time-reflection sy…
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…
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…
