Abstract In underdoped cuprates, T c is thought to be determined by Cooper pair phase fluctuations because of the small superfluid density n s . Experimentally, T c is found to scale with n s . The fluctuation-exchange approximation (FLEX) in its standard form fails to predict this behavior of T c since it does not include phase fluctuations. We therefore extend the FLEX to include them self consistently. We present results for T c[n s, x], where x is the doping.
