A Note on Corrections to Entanglement Wedge Reconstruction
Edward Witten
If entanglement wedge reconstruction is exact, then (under certain assumptions) the area term in the RT formula is a c-number, indicating that the choice of a bulk quantum state do…
Localization of strings on group manifolds
Sameer Murthy, Edward Witten
We compute the partition function of the WZW model with target a compact Lie group by adapting a method used by Choi and Takhtajan to compute the heat kernel of the group manif…
Introduction to Black Hole Thermodynamics
Edward Witten
These notes aim to provide an introduction to the basics of black hole thermodynamics. After explaining Bekenstein's original proposal that black holes have entropy, we discuss Haw…
Instantons and the Large N=4 Algebra
Edward Witten
We investigate the differential geometry of the moduli space of instantons on S^3 x S^1. Extending previous results, we show that a sigma-model with this target space can be expect…
Scale and Conformal Invariance in 2d Sigma Models, with an Application to N=4 Supersymmetry
Georgios Papadopoulos, Edward Witten
By adapting previously known arguments concerning Ricci flow and the c-theorem, we give a direct proof that in a two-dimensional sigma-model with compact target space, scale invari…
