Thermodynamic and transport properties of underdoped cuprates from ARPES data

Abstract

he relationship between photoemission spectra of high-$T_{\text{c}}$ cuprates and their thermodynamic and transport properties are discussed. The doping dependence of the expected quasi-particle density at the Fermi level ($E_{\mathrm{F}}$) are compared with the electronic specific heat coefficient $\gamma$ and that of the spectral weight at $E_{\mathrm{F}}$ with the in-plane and out-of-plane superfluid density. We have estimated the electrical resistivity of underdoped cuprates from the momentum distribution curve (MDC) at $E_{\mathrm{F}}$ in the nodal direction. The temperature dependence of the MDC width is also consistent with that of the electrical resistivity.
