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...

Abstract: Tidal deformabilities serve as an effective tool to study the structures of compact objects. In the first part of the talk, I will present how the worldline effective field theory (EFT) can be applied to examine the tidal responses of...

Abstract: Inflation, the theory describing a period of exponential superluminal expansion in the early universe, is both a proposed solution to the large-scale structure we see in our night sky and a mystery of which we have little experimental...
