Metallic stripes: separation of spin-, charge-, and string fluctuation
  Inspired by the cuprate stripes, the problem of a one dimensional metal living on a delocalized trajectory in two dimensional space is considered. Under the assumption that a localized and charge incompressible reference string state exists, the long wavelength theory is deduced which corresponds to a Luttinger liquid with an additional sector of independent string modes.
