Supersymmetry and d-Wave Superconductivity
  Motivated by a recent development in the field theory of the fractional quantum Hall effect, we propose a supersymmetric field theoretical model of quantum critical d-wave and (d+id)-wave superconductors. New concept is a composite particle with the supercharge which is formed by electron (hole) and supersymmetric collective configurations of spin and charge. Quantum critical d-wave superconductor is characterized as the condensate of these composite particles.
