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…
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…
Cartan-like formulation of electric Carrollian gravity
Simon Pekar, Alfredo Pérez, Patricio Salgado-Rebolledo
We present a Cartan-like first-order action principle for electric Carrollian gravity. The action is invariant under the local homogeneous Carroll group, albeit in a different repr…
Galilei particles revisited
José Miguel Figueroa-O'Farrill, Simon Pekar, Alfredo Pérez +1
We revisit the classifications of classical and quantum galilean particles: that is, we fully classify homogeneous symplectic manifolds and unitary irreducible projective represent…
Fracton infrared triangle
Alfredo Pérez, Stefan Prohazka, Ali Seraj
In theories with conserved dipole moment, isolated charged particles (fractons) are immobile, but dipoles can move. We couple these dipoles to the fracton gauge theory and analyze…
