Quantum smectic as a dislocation Higgs phase.
The theory describing quantum smectics in 2+1 dimensions, based on topological quantum melting is presented. This is governed by a dislocation condensate characterized by an ordering of Burger's vector and this "dual shear superconductor" manifests itself in the form of a novel spectrum of phononlike modes.
