Query: Functional-integral approach to Coulomb fluids in the strong coupling
  limit   We have developed a field theory for strongly coupled Coulomb fluids, via
introducing new functional--integral transformation of the electrostatic
interaction energy. Our formalism not only reproduces the Lieb--Narnhofer lower
bound, but also bridges logical gaps which previous approaches have involved.
