In solid state physics, by super-insulators one refers to meaterials which at very low but non-vanishing temperature have effectively unbounded electrical resistance. This phenomenon may be understood as the “EM-dual” to that of superconductors.
Generalized to color charge, this notion plays a central role in the dual superconductor model of confinement.
