Abstract
The BCS superconductivity to Bose condensation crossover problem is studied in two dimensions in S, P, and D waves, for a simple anisotropic pairing, with a finite-range separable potential at zero temperature. The gap parameter and the chemical potential as a function of Cooper-pair binding Bc exhibit universal scaling. In the BCS limit the results for coherence length j and the critical temperature Tc are appropriate for highTc cuprate superconductors and also exhibit universal scaling as a function of Bc . @S0163-1829~97!02501-0#
