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…
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…
Planons and their Carroll-Galilei symmetries
José Figueroa-O'Farrill, Simon Pekar, Alfredo Pérez +1
We study the dynamics of planons, particles whose mobility is restricted to a plane, through the classification of coadjoint orbits and unitary irreducible representations of the c…
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…
Fractons on curved spacetime in dimensions
Jelle Hartong, Giandomenico Palumbo, Simon Pekar +2
We study dipole Chern-Simons theory with and without a cosmological constant in dimensions. We write the theory in a second order formulation and show that this leads to a fr…
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…
