Operator Product Expansion in Carrollian CFT
Kevin Nguyen, Jakob Salzer
Carrollian conformal field theory offers an alternative description of massless scattering amplitudes, that is holographic in nature. In an effort to build a framework that is both…
Energy Detectors and Asymptotic Symmetries
Hernán A. González, Jakob Salzer
We study detector operators measuring energy to a power at null infinity in four-dimensional gauge theories and gravity. These operators transform as conformal primaries on…
Soft gravitons in three dimensions
Jordan Cotler, Kristan Jensen, Stefan Prohazka +2
We consider quantum gravity with zero cosmological constant in three dimensions. First, we show that pure quantum gravity can be written as a magnetic Carrollian theory living on n…
Quantizing Carrollian field theories
Jordan Cotler, Kristan Jensen, Stefan Prohazka +3
Carrollian field theories have recently emerged as a candidate dual to flat space quantum gravity. We carefully quantize simple two-derivative Carrollian theories, revealing a stro…
