Constraints on RG Flows from Holographic Entanglement Entropy
Sera Cremonini, Xi Dong
We examine the RG flow of a candidate c-function, extracted from the holographic entanglement entropy of a strip-shaped region, for theories with broken Lorentz invariance. We clar…
Holographic Entanglement Entropy for General Higher Derivative Gravity
Xi Dong
We propose a general formula for calculating the entanglement entropy in theories dual to higher derivative gravity where the Lagrangian is a contraction of Riemann tensors. Our fo…
Holographic entanglement beyond classical gravity
Taylor Barrella, Xi Dong, Sean A. Hartnoll +1
The Renyi entropies and entanglement entropy of 1+1 CFTs with gravity duals can be computed by explicit construction of the bulk spacetimes dual to branched covers of the boundary…
Mathieu Moonshine and N=2 String Compactifications
Miranda C. N. Cheng, Xi Dong, John F. R. Duncan +3
There is a `Mathieu moonshine' relating the elliptic genus of K3 to the sporadic group M_{24}. Here, we give evidence that this moonshine extends to part of the web of dualities co…
