Fracton topological order, discovered recently in various exactly solvable models, represents a new class of three-dimensional topologically ordered phases. These models sit at the intersection of several sub-fields, including topological order, glassy dynamics and many body localization, quantum information, and higher rank gauge theories. 

These phases exhibit an intriguing phenomenology, supporting immobile excitations ("fractons"), excitations whose motion is restricted to sub-dimensional manifolds, and a sub-extensive topological degeneracy. In this talk, I will discuss the current understanding of fractons, focusing in particular on their quantum dynamics and on the question of whether (and how fast) they thermalize.
