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...

Abstract: I will give an overview of recent activity based on the idea that we can test quantum properties of the gravitational field in experiments. I will emphasize the need to state precisely what hypotheses are being tested by showing some...

Abstract: I will discuss the general framework of effective theories obtained via exact path integration of a complete theory over some sector of its degrees of freedom.Theories constructed this way contain multi-integrals which couple fields...
