Volume dependence of the superconducting transition temperature of aluminum calculated from a first-principles potential

Using a first-principles, local, volume-dependent pseudopotential which has been used successfully to calculate several properties of aluminum, we have calculated the electron-phonon interaction for this material. From this information we have calculated the volume dependence of the superconducting transition temperature. The pseudopotential is constructed from the nonlinear induced density around an aluminum ion in an electron gas. The volume dependence is introduced by the electron-gas density parameter r/sub s/
