Pauli Lectures 2022
The Wolfgang Pauli Lectures 2022 were dedicated to Physics.
Professor Juan M. Maldacena
Institute for Advanced Study, Princeton, USA
Juan Maldacena (September 10, 1968 in Buenos Aires, Argentina) is a theoretical physicist. He made significant contributions to the foundations of string theory and quantum gravity. His most famous discovery is the AdS/CFT correspondence, a realization of the holographic principle in string theory.
Black holes and the structure of spacetime

Black holes are fascinating objects where the deformation of spacetime gives surprising effects. When quantum effects are taken into account, black holes emit Hawking radiation, which leads to interesting paradoxes. Work on these paradoxes has led to surprising connections between entanglement and the geometry of spacetime.
Black hole entropy and quantum information

Lecture Hall HCI G 3, ETH Hönggerberg, Vladimir-Prelog-Weg 1-5 / 10, Zurich
Black holes have an entropy. We will discuss two kinds of entropy that we can assign to a black hole, the thermodynamic entropy and the exact quantum entropy. We will explain how to compute them in terms of the areas of some surfaces plus some quantum corrections, and discuss how these formulas suggest that the information comes out of black holes.
The entropy of Hawking radiation

Lecture Hall HIL E 1, ETH Hönggerberg, Stefano-Franscini-Platz 5, Zurich
We set up the Hawking information paradox for a simple black hole configuration. We compute the gravitational fine grained entropy of the black hole. After the Page time, the entanglement wedge of the radiation includes most of the black hole interior. We explain how this arises from replica wormholes.
