Abstract: I will briefly review the factorisation of soft and collinear singularities in massless gauge theory amplitudes, and the structure of the soft anomalous dimension matrix. I will then discuss the implications of this factorisation for the...

Abstract: I will review and revisit the quantum entropy of supersymmetric black holes, which is defined as a gravitational path integral in the near-horizon AdS2 region.

This has been studied in the past using different methods: loop calculations...

Abstract: A black hole, when observed from outside, can be represented as a quantum system of microstates. For AdS black holes, the microstates are dual to operators in the boundary CFT by the AdS/CFT correspondence. In this talk, I will discuss the...

Abstract: The key word in the title is “IN”. Unlike AdS where observers can be thought of as living on the boundary of space, or even in a laboratory beyond the boundary, in dS the observer is part of the system; he or she lives “in” the de Sitter...

The Institute for Advanced Study requires that all adult visitors, collaborators, conference and on-campus seminar attendees and outside vendors coming to the Institute are required to have completed a COVID-19 vaccination and booster in order to...

Abstract: The amplitudes for soft gauge boson emission are related to the non-radiative amplitudes via soft theorem. The soft limit of gauge theories and perturbative gravity are surprisingly similar despite the different gauge structures. However...

Abstract: In this talk I describe work in progress on a proposed definition of T Tbar deformed holographic CFT on Rindler space. The construction employs the reformulation of T Tbar deformed in terms of flat JT gravity, and combines elements of the...
