Abstract

We explore a BCS Bose Einstein crossover scenario for 0 ≤ T ≤ T_c and its implications for the superfluid density and specific heat. The low lying excitations consist of nodal (fermionic) quasi-particles as well as excited (bosonic) pair states. Semi-quantitative comparison with cuprate data is reasonable, with no compelling indications for Landau parameter effects.
