In theories with conserved dipole moment, isolated charged particles (fractons) are immobile, but dipoles can move. In this talk, I will show how to couple these dipoles to the fracton gauge theory and analyze the universal infrared structure. This uncovers an observable double kick memory effect that is related to a novel dipole soft theorem. Together with their asymptotic symmetries this constitutes the first realization of an infrared triangle beyond Lorentz symmetry. This demonstrates the robustness of these IR structures and paves the way for their investigation in condensed matter systems and beyond. The talk is based on arXiv: 2310.16683 [hep-th].
