The OPE Randomness Hypothesis and Euclidean Wormholes
ASC Workshops - April 06, 2021 16:18 - 1 hour - Video ★★★★★ - 1 ratingRecent developments in holography indicate that the semi-classical Euclidean path-integral of Einstein gravity is much more powerful than previously anticipated. It is capable of reproducing a unitary Page curve for black hole evaporation, and can even capture some features of the discrete natu...
The principle of holography of information and its low-energy tests
ASC Workshops - April 06, 2021 16:18 - 1 hour - Video ★★★★★ - 1 ratingThe principle of holography of information states that, in any theory of quantum gravity, a copy of all the information available on a Cauchy slice is also available near the boundary of the slice. This principle can be made precise and proved, under weak assumptions, for theories of gravity in A...

The Unreasonable Effectiveness of Higher-Derivative Supergravity in AdS_4 Holography
ASC Workshops - April 06, 2021 16:18 - 54 minutes - Video ★★★★★ - 1 ratingI will describe the four-derivative corrections to four-dimensional N=2 minimal gauged supergravity and show that they are controlled by two constants. Interestingly, the solutions of the equations of motion in the two-derivative theory are not modified by the higher-derivative corrections. I wil...

Topological partition functions and (iterated) integrals of modular forms
ASC Workshops - April 06, 2021 16:18 - 1 hour - Video ★★★★★ - 1 ratingAs a consequence of electric-magnetic duality, partition functions of four-dimensional gauge theories can be expressed in terms of modular forms in many cases. I will discuss new results for the modularity of topologically twisted partition functions of N=2 and N=4 supersymmetric theories, and in...

Towards a microscopic model of AdS fragmentation
ASC Workshops - April 06, 2021 16:18 - 55 minutes - Video ★★★★★ - 1 ratingA salient feature of black holes near extremality is the appearance of an AdS2 throat in their near-horizon geometry. Depending on the underlying theory, these AdS2 throats may be unstable to fragmentation, wherein a single throat is instead replaced by a tree-like structure of branched AdS2 thro...
Towards a Swampland Global Symmetry Conjecture
ASC Workshops - April 06, 2021 16:18 - 1 hour - Video ★★★★★ - 1 ratingGiven that exact global symmetries are forbidden by quantum gravity, it is natural to expect that bounds on the quality of approximate global symmetries exist. So far, holographic arguments have only been provided for the former claim. I will discuss a classification of approximate global symmetr...

Vortices , wall-crossing and 3d Seiberg like dualities
ASC Workshops - April 06, 2021 16:18 - 57 minutes - Video ★★★★★ - 1 ratingWe explore 1d vortex dynamics of 3d supersymmetric Yang-Mills theories, as inferred from factorization of exact partition functions. Under Seiberg-like dualities, the 3d partition function must remain invariant, yet it is not a priori clear what should happen to the vortex dynamics. We observe th...

A Wheeler DeWitt approach for Liouville quantum gravity
ASC Workshops - April 06, 2021 16:18 - 56 minutes - Video ★★★★★ - 1 ratingI will present the connection between the Wheeler-DeWitt approach for two-dimensional quantum gravity and holography, focusing in the case of Liouville theory coupled to c = 1 matter. The analysis is in a spirit similar to the recent studies of Jackiw-Teitelboim gravity. Matrix quantum mechanics ...
