Topological entanglement entropy in 3D gravity
Vijay Balasubramanian, Charlie Cummings
We derive an entropy formula for a recently proposed tensor network model of states in 3D gravity which satisfy the constraint equations of diffeomorphism invariance, and including…
Entanglement entropy in topological tensor networks
Vijay Balasubramanian, Charlie Cummings
We derive an entropy formula for recently proposed tensor network models which prepare diffeomorphism invariant states of topological quantum field theories with non-compact and/or…
The Topological Equivalence Principle: On Decoupling TFTs from Gravity
Charlie Cummings, Jonathan J. Heckman
Topological field theories (TFTs) play an important role in characterizing the deep infrared (IR) of many quantum systems with a mass gap, as well as the global symmetries of quant…
Diffeomorphism invariant tensor networks for 3d gravity
Vijay Balasubramanian, Charlie Cummings
Tensor networks prepare states that share many features of states in quantum gravity. However, standard constructions are not diffeomorphism invariant and do not support an algebra…
Purely GHZ-like entanglement is forbidden in holography
Vijay Balasubramanian, Monica Jinwoo Kang, Charlie Cummings +2
We provide evidence that three-party entanglement signals in holography obey a relation that is not satisfied by generalized Greenberger-Horne-Zeilinger (GHZ) states. Using propose…
Entanglement in Typical States of Chern-Simons Theory
Charlie Cummings
We compute various averages over bulk geometries of quantum states prepared by the Chern-Simons path integral, for any level and compact simple gauge group . We do so by car…
Multipartite Entanglement Structure of Fibered Link States
Vijay Balasubramanian, Charlie Cummings
We study the patterns of multipartite entanglement in Chern-Simons theory with compact simple gauge group and level for states defined by the path integral on ``link comple…
The entropy of finite gravitating regions
Vijay Balasubramanian, Charlie Cummings
We develop a formalism for calculating the entanglement entropy of an arbitrary spatial region of a gravitating spacetime at a moment of time symmetry. The crucial ingredient is a…
