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.
