Note On The Dilaton Effective Action And Entanglement Entropy
Shamik Banerjee
In this note we do the analysis of entanglement entropy more carefully when the non-conformal theory flows to a non-trivial IR fixed point. In particular we emphasize the role of t…
Trace Anomaly Matching and Exact Results For Entanglement Entropy
Shamik Banerjee
Following the ideas developed by Komargodski and Schwimmer in arXiv:1107.3987 and arXiv:1112.4538, we argue that the IR dilaton effective action on the cone computes the entangleme…
Nonlinear constraints on gravity from entanglement
Shamik Banerjee, Apratim Kaviraj, Aninda Sinha
Using the positivity of relative entropy arising from the Ryu-Takayanagi formula for spherical entangling surfaces, we obtain constraints at the nonlinear level for the gravitation…
Constraining gravity using entanglement in AdS/CFT
Shamik Banerjee, Arpan Bhattacharyya, Apratim Kaviraj +2
We investigate constraints imposed by entanglement on gravity in the context of holography. First, by demanding that relative entropy is positive and using the Ryu-Takayanagi entro…
