Carrollian quantum states and flat space holography
Stefan Fredenhagen, Stefan Prohazka, Robert Tiefenbacher
We study free Carrollian quantum field theories from an algebraic perspective and explore their implications for flat space holography. As explicit examples, we construct the elect…

Holographic realization of higher-spin Carrollian free fields
Ethan D'Arcy, Arnaud Delfante, Stefan Fredenhagen
We provide a holographic bulk realization of Carrollian free-field structures arising in three-dimensional asymptotically flat (higher-spin) gravity. We construct a class of bounda…

Free-field construction of Carrollian -algebras
Stefan Fredenhagen, Lucas Hörl
We study Carrollian contractions of -algebras from a free-field perspective. Using a contraction of the Miura transformation, we obtain explicit free-field realizations of the…
