abstract   = "The d-dimensional complex Ginzburg-Landau (GL) model 
              is solved according to a variational method by separating 
              phase and amplitude. The GL transition becomes first order 
              for high superfluid density because of effects of phase 
              fluctuations. We discuss its origin with various arguments showing 
              that, in particular for d = 3, the validity 
              of our approach lies precisely in the first order domain.",
