The ordered limit of superconductivity

The conventional understanding of superconductivity rests heavily on the physics of Bose gases. In the high temperature superconductors, the superfluid is very strongly correlated being on the verge of solidifying into a stripe phase. Inspired by this problem, we employ quantum field theory techniques to construct the limit of "optimally ordered" superconductivity. These superconductors can be viewed as quantum elastic entities different from normal crystals in the sense that they lost their rigidity against shear stress as dual Bose condensates of quantum dislocations. Exciting new physical properties emerge which can, in principle, be measured although they invoke unconventional experiments: quantum liquid crystalline orders, oscillations of magnetic screening currents, and new collective modes found in the dynamical electromagnetic response.
