A residual linear term is observed in the thermal conductivity of optimally doped Bi 2Sr2CaCu2O8 at very low temperatures whose magnitude is in excellent agreement with the value expected from Fermi-liquid theory and the d-wave energy spectrum measured by photoemission spectroscopy with no adjustable parameters. This solid basis allows us to make a quantitative analysis of thermodynamic properties at low temperature and establish that thermally excited quasiparticles are a significant, perhaps… CONTINUE READING
