A New Generalization of Entanglement Entropy by Tadashi Takayanagi

Explore a cutting-edge colloquium on the generalization of entanglement entropy presented by Tadashi Takayanagi from the Yukawa Institute for Theoretical Physics at Kyoto University. Delve into the concept of holography in string theory and its application to simplify geometric computations of entanglement entropy. Discover how this approach extends the Bekenstein-Hawking formula for black hole entropy and suggests that gravitational spacetime is composed of quantum entanglement bits. Gain insights into recent advancements in the field, focusing on the newly introduced concept of pseudo entropy, its relationship to entanglement entropy, and its explicit gravity dual. Enhance your understanding of theoretical physics and quantum information theory in this 78-minute online lecture hosted by the International Centre for Theoretical Sciences.
