Temperature dependence of superfluid weights for high Tc cuprates

Using the recently proposed holon-pair boson theory of the t–J Hamiltonian [Phys. Rev. B 64 (2001) 052501] that we developed recently, we report the temperature dependence of the superfluid weight. It is shown that at low hole doping concentration x and at low temperatures T there exists a propensity of a linear decrease of the superfluid weight ns/m∗ with temperature, and a tendency of doping independence in the slope of nsm∗(x,T) vs. T in accordance of the relation nsm∗(x,T)=nsm∗(x,0)−αT with α, a constant.
