Abstract

I will summarize some recent results on systems of dipole-conserving point particles, 'fractons'. These exhibit non-equilibrium dynamics characterized by attractors, that cannot be characterized by Gibbsean statistical mechanics. Fracton dynamics generically possess a 'Janus pont' of low complexity around which a bidirectional arrow of time naturally obtains. Its Boltzmann entropy is unbounded and thus the dynamics evades 'heat death' at late times, suggesting a surprisingly clean resolution of the arrow-of-time paradox in non-equilibrium dynamics.
