Abstract: Scattering amplitudes can be used to probe the all-orders structure of gauge theories. Particularly rich is the non-planar sector, where physical phenomena such as quadrupole radiation and multi-reggeon interactions appear. In this talk I...

Abstract: Is it possible to read off the quantum gravity dual of a CFT directly from its operator algebra? In this talk, I will present a step-by-step recipe for building up 3D quantum spacetimes dual to 2D CFTs, synthesizing results and techniques...

Abstract: In this talk, we'll review the bootstrap method that uses unitarity and causality (analyticity + crossing) to constrain low-energy effective field theories (EFTs), especially those including gravitational couplings. This method allows us...

Abstract: We study the operator algebra of extended conformal defects in more than two spacetime dimensions. Such algebra structure encodes the combined effect of multiple impurities on physical observables at long distances as well as the...

Abstract: Black hole X-ray binaries and Active Galactic Nuclei transition through a series of accretion states in a well-defined order. During a state transition, the accretion flow changes from a hot geometrically thick accretion flow, emitting a...

Abstract: The Gaiotto-Moore-Witten "Algebra of the Infrared" allows one to construct the category of supersymmetric boundary conditions for a wide class of massive N=(2,2) QFTs in two dimensions. In particular, it applies to N=(2,2) QFTs defined by...

Abstract: Earthquakes exhibit complex behavior at all scales, from the evolution of slip during a single rupture lasting seconds to minutes, to the statistics of regional seismicity over years or centuries. The origin of complexity in fault behavior...

Abstract: I will discuss consequences of the loss of the “additivity” property of QFT in the large N limit of Holographic CFTs. I will demonstrate how the additivity anomaly underlies the success of quantum error correcting code models of holography...

Abstract: A clear outcome of Snowmass 2021 and now the US P5 report was the community support for R&D towards a future muon collider. In this talk we will discuss the general physics program that becomes available to the community during the...
