Stefan Prohazka: Fracton Infrared Triangle

Title: Fracton Infrared Triangle Abstract: In theories with conserved dipole moment, isolated charged particles (fractons) are immobile, but dipoles can move. I will show how these dipoles coupled to the fracton gauge theory lead to an universal infrared structure. This uncovers an observable double kick memory effect which we will relate to a novel dipole soft theorem. Together with their asymptotic symmetries this constitutes the first realization of an infrared triangle beyond Lorentz symmetry. This also demonstrates the robustness of these IR structures and paves the way for their investigation in condensed matter systems and beyond.
