Title: Comments on holographic entanglement entropy in $T T$ deformed conformal field theories

Abstract

The Ryu-Takayanagi (RT) formula has been a key ingredient in our understanding of holography. Recent work on $T T$ deformations has also boosted our understanding of holography away from the conformal boundary of AdS. In this short note, we aim to refine some recent work demonstrating the success of the RT formula in $T T$ deformed theories. We emphasize general arguments that justify the use of the RT formula in general holographic theories that obey a Gubser-Klebanov-Polyakov-Witten (GKPW)-like dictionary. In doing so, we clarify subtleties related to holographic counterterms and discuss the implications for holography in general spacetimes.
