Classical Limit of Large N Gauge Theories with Conformal Symmetry

arXiv:1907.05419 · doi:10.1007/JHEP02(2020)021

Abstract

In this paper we study classical limit of conformal field theories realized by large N gauge theories using the generalized coherent states. For generic large N gauge theories with conformal symmetry, we show that the classical limit of them is described by the classical Einstein gravity. This may be regarded as a kind of derivation of the AdS/CFT correspondence.
