Superconducting Dark Matter
  We extend recently proposed mimetic dark matter (DM) and dust of dark energy
(DE) models to a U(1)-charged gauged scalar field. This extension yields a mass
to the photon via the Higgs mechanism. The square of this photon mass is
proportional to the DM energy density. Thus dense DM environments can screen
the dark vector force. There is a substantial freedom in this gauged extension
of the irrotational fluid-like DM. This freedom enables one to model the
classical London equation of superconductivity or to obtain the photon mass
which remains constant during the matter-dominated \'epoque.
