When left to their own devices, interacting quantum systems generally thermalize, reaching a state that appears featureless to local observers. However, a system can approach this equilibrium in a variety of ways. Typically, conserved charges diffuse across the system, but in the presence of mobility constraints, this diffusion can be slowed or even halted entirely. In this talk, I will discuss the out-of-equilibrium dynamics of fractonic systems with dipole conservation. As single charges cannot move in isolation, dipole conservation stands in tension with ordinary thermalization. With an eye towards recent experiments in cold atom platforms, which natively host power-law decaying interactions, I will concentrate on the interplay between these long-range interactions, which speed up thermalization, with dipole constraints on mobility, which slow it down.
