Abstract
Effective models for fracton gauge fields can be constructed by gauging extensions of the Aristotelian algebra that include an Abelian charge and its associated dipole moment. Alternatively, such gauge theories can be obtained from Cosserat elasticity via dualization. Using the relation between dipole preserving symmetries and Carrollian algebras, these models can be generalized to describe higher-rank gauge fields that naturally couple to line-like fracton excitations, or fracton strings.
