Study of the Phase Diagram and the Tc Pressure Dependence for HgBaCuO Superconductors

Abstract

We apply a method recently derived based on the extended Hubbard Hamiltonian and the BCS approach to obtain the superconducting critical temperature dependence with carrier density for the HgBaCuO compounds. We show that this procedure can be used to study pressure effect with the assumption that pressure changes the supercondutor gap. The results reproduce well the experimental data for the whole doping regime and the high and low pressure dependence.
