Abstract

We consider the variational approach to Luttinger liquids in one- and two dimensions. In one dimension the 1/r 2 model solved by Sutherland is considered and shown to include Luttinger-Liquid type correlations. For the two dimensional t — J a wavefunction is introduced which is shown to have an algebraic singularity at the Fermi edge in the momentum distribution function. The possible coexistence of Luttinger Liquid correlations with d-wave superconductivity is discussed.
