text: "Kinetic constraints are generally expected to slow down dynamics in many-body
systems, obstructing or even\r\ncompletely suppressing transport of conserved
charges. Here, we show how gauge theories can defy this wisdom\r\nby yielding
constrained models with faster-than-diffusive dynamics. We first show how, upon
integrating out\r\nthe gauge fields, one-dimensional U(1) lattice gauge theories
are exactly mapped onto XX models with nonlocal\r\nconstraints. This class of
kinetically constrained models interpolates between free theories and highly constrained\r\nlocal
fermionic models. We find that energy transport is superdiffusive over a broad
parameter regime. Even\r\nmore drastically, spin transport exhibits ballistic
behavior, albeit with anomalous finite-volume properties as a\r\nconsequence of
gauge invariance. Our findings are relevant to current efforts in quantum simulations
of gauge theory dynamics and anomalous hydrodynamics in closed quantum many-body
systems."
