Abstract

The electronic dispersion for Bi₂Sr₂CaCu₂O_8+\ensuremathδ has been determined from angle-resolved photoemission spectroscopy (ARPES). From this dispersion, we calculate the entropy and superfluid density. Even with no adjustable parameters, we obtain an exceptional match with experimental data across the entire phase diagram, thus indirectly confirming both the ARPES and thermodynamic data. The van Hove singularity is crossed in the overdoped region, giving a distinctive linear-in-T temperature dependence in the superfluid density there.
