Fracton Infrared Triangle in Dipole-Conserving Theories

Explore the intricacies of fracton gauge theory and its implications in this 42-minute conference talk delivered by Alfredo Perez at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the fascinating world of theories with conserved dipole moment, where isolated charged particles (fractons) are immobile, but dipoles can move freely. Discover how to couple these dipoles to the fracton gauge theory and uncover the universal infrared structure that emerges. Learn about the observable double kick memory effect and its relation to a novel dipole soft theorem. Examine the first realization of an infrared triangle beyond Lorentz symmetry, demonstrating the robustness of these IR structures. Gain insights into potential applications in condensed matter systems and beyond. This talk, based on arXiv: 2310.16683 [hep-th], was part of the Thematic Programme on "Carrollian Physics and Holography" held at the ESI in April 2024.
