Query: Deconfining the rotational Goldstone mode: the superconducting nematic
  liquid crystal in 2+1D   The Goldstone theorem states that there should be a massless mode for each
spontaneously broken symmetry generator. There is no such rotational mode in
crystals, however superconducting quantum nematics should carry rotational
Goldstone modes. By generalization of thermal 2D defect mediated melting theory
into a 2+1D quantum duality, the emergence of the rotational mode at the
quantum phase transition from the solid to the nematic arises as a
deconfinement phenomenon, with the unusual property that the stiffness of the
rotational mode originates entirely in the dual dislocation condensate.
