Speaker: Davide Iacobacci, PhD student at SSM, Naples, who is going to talk about Entanglement Entropy in the framework of AdS-CFT correspondence.
Abstract: We delve into the interplay between quantum information theory and gravitational physics, focusing on the Ryu-Takayanagi (RT) formula within the framework of the AdS/CFT correspondence. We begin with a historical overview of holography, tracing key developments from 't Hooft and Susskind's early insights to Maldacena's AdS/CFT duality. The core of the presentation explores entanglement entropy, providing an intuitive understanding and highlighting its significance in quantum field theory (QFT) and many-body systems. We then introduce the RT formula, illustrating its role in linking entanglement entropy to minimal surfaces in anti-de Sitter (AdS) space. Through concrete examples, including the AdS3/CFT2 correspondence and black hole cases, we demonstrate the practical calculations and implications of this relationship. The presentation concludes by emphasising the broader impact of these concepts, underscoring the essential role of entanglement in understanding quantum phenomena. We end with a new quantum information theoretic view for studying gravitational back-reaction.
