Nodal Quasiparticles versus Phase Fluctuations in High Tc Superconductors: An Intermediate Scenario

Abstract

We explore a BCS Bose Einstein crossover scenario for $0\le T\le T_c$ 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.
