Algebra of operators in an AdS-Rindler wedge

High Energy Physics - Theory 2023-07-04 v3

Abstract

We discuss the algebra of operators in AdS-Rinlder wedge, particularly in AdS5_{5}/CFT4_{4}. We explicitly construct the algebra at N=N=\infty limit and discuss its Type III1_{1} nature. We will consider 1/N1/N corrections to the theory and using a novel way of renormalizing the area of Ryu-Takayanagi surface, describe how several divergences can be renormalized and the algebra becomes Type II_{\infty}. This will make it possible to associate a density matrix to any state in the Hilbert space and thus a von Neumann entropy.
