Superfluid memory effect
Kristan Jensen, Alfredo Pérez, Stefan Prohazka
We identify a memory effect produced by phonon scattering in a superfluid: a localized scattering event generates a far-field pressure pulse with vanishing time integral but a nonz…
Inner products and closed universes
Jordan Cotler, Kristan Jensen
We study overlaps of late-time states in semiclassical de Sitter quantum gravity. In a family of deformations of de Sitter JT gravity, we compute the no-boundary wavefunction to on…
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…
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…
