From pp-Waves to Galilean Spacetimes
José Figueroa-O'Farrill, Ross Grassie, Stefan Prohazka
We exhibit all spatially isotropic homogeneous Galilean spacetimes of dimension , including the novel torsional ones, as null reductions of homogeneous pp-wave spacet…
The gauging procedure and carrollian gravity
José Figueroa-O'Farrill, Emil Have, Stefan Prohazka +1
We discuss a gauging procedure that allows us to construct lagrangians that dictate the dynamics of an underlying Cartan geometry. In a sense to be made precise in the paper, the s…
Lifshitz symmetry: Lie algebras, spacetimes and particles
José Figueroa-O'Farrill, Ross Grassie, Stefan Prohazka
We study and classify Lie algebras, homogeneous spacetimes and coadjoint orbits ("particles") of Lie groups generated by spatial rotations, temporal and spatial translations and an…
Asymptotic symmetries and soft charges of fractons
Alfredo Pérez, Stefan Prohazka
The asymptotic structure of gauge theories describing fracton interactions is analyzed. Two sets of asymptotic conditions are proposed. Both encompass all known solutions, lead to…
