Description

We consider the effect of fluctuations of the superconducting dx2-y2-wave gap above Tc for the 2D Hubbard model. The order parameter fluctuations (OPFL) lead to a decrease of Tc and to a suppression of the increasing strength of OPFL, or decreasing doping. The resulting neutron T. This agrees qualitatively with the observed spin gap behavior in the underdoped high-Tc cuprates. (orig.)
