Abstract
Scanning-tunneling spectroscopy studies on suggest the presence of electronic inhomogeneity with a large spatial variation in gap size. have modeled this variation by assuming a spatially varying pairing interaction. We show that their calculated specific heat is incompatible with the experimental data which exhibit narrow transitions. This calls into question the now-common assumption of gap and pairing inhomogeneity.
