During this talk\, we will explore how conserving quantities influence the long-timedynamics of generally strongly interacting closed systems. Typically\, interactingq uantum systems achieve thermalization via their own unitary dynamics\, lea ding tothe emergence of statistical mechanics. However\, the route to equi librium can differdue to the existence of conserved quantities.

Often\, conserved charges spread diffusively across the system. However\, mobilityconstraints can impede or even halt their dynamics. The initial pa rt of the talk isdevoted to the non-equilibrium dynamics of fractonic syst ems\, especially those withmultiple conservation laws\, such as dipole con servation. In these systems\, charges areunable to move independently.

Their limited dynamics are described by a generalizeddiffusion equa tion that exhibits sub-diffusion [1]. In the second half of the talk\, ins pired by recent experiments on trapped-ion platformsthat intrinsically dis play power-law decaying interactions [2]\, we will delve into theinterplay between long-range interactions that promote thermalization and the dipol emobility constraints that obstruct it [3].
