Carrollian holographic duals are non-local
Jordan Cotler, Prateksh Dhivakar, Kristan Jensen
Mapping the -matrix of a generic theory of flat space gravity coupled to matter to correlation functions of a putative Carrollian dual, we show that bulk interactions imply boun…
Norm of the no-boundary state
Jordan Cotler, Kristan Jensen
We consider Einstein gravity with positive cosmological constant coupled to matter in an asymptotically de Sitter universe with sphere boundary at timelike infinity. In this settin…
A finite Carrollian critical point
Jordan Cotler, Prateksh Dhivakar, Kristan Jensen
We construct examples of renormalizable Carrollian theories with finite effective central charge and non-trivial dynamics. These include critical points that are not scale-invarian…
Holographic observers for time-band algebras
Kristan Jensen, Suvrat Raju, Antony J. Speranza
We study the algebra of observables in a time band on the boundary of anti-de Sitter space in a theory of quantum gravity. Strictly speaking this algebra does not have a commutant…
The Fractional Hall hierarchy from duality
Kristan Jensen, Amir Raz
We show that a modified version of Son's Dirac composite fermion theory proposed by Seiberg et al gives a candidate unified description of the gapped and gapless fractional quantum…
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…
