Carrollian origin of spacetime subsystem symmetry

We propose that models with spacetime subsystem symmetry are connected to Lorentz invariant models via the Carrollian limit. In this way, a recently proposed model with spacetime subsystem symmetry was readily reproduced together with its conserved charges. We then couple this model to a dynamical Abelian gauge field and Carroll gravity. Our procedure can be applied in arbitrary dimensions and paves the way to construct new models with spacetime subsystem symmetry.

We propose that models with spacetime subsystem symmetry are connected to Lorentz invariant models via the Carrollian limit. In this way, the recently proposed model with spacetime subsystem symmetry can be reproduced along with its conserved charges. We then couple this model to a dynamical Abelian gauge field and Carroll gravity. Our procedure is applicable in arbitrary dimensions and paves the way for constructing new models with spacetime subsystem symmetry.
