The strong electron correlation in the cuprates can lead to an enhanced effective mass for both bosonic and fermionic quasiparticles. Where this correlation is characterized by a length that is inversely proportional to the effective temperature, the thermal wavelength for the bosonic quasiparticles becomes essentially independent of temperature. Applying this concept to a preformed pair model, such as the (Cu)13 cluster model, gives Tc vs dopant curves and superconducting gaps in good agreement with experiment. In addition, a correlation-enhanced effective mass provides a natural explanation for the anomalous normal state resistivity and optical conductivity of the cuprates.
