We show that the current-density functional theory for superconductors(sc-CDFT) can describe the magnetic-field-induced first-order phase transitionof aluminum from a superconducting state to a normal state. This isaccomplished by introducing a model for the magnetic field dependence of theattractive interaction between superconducting electrons. This model statesthat the surface potential well produced by the penetrating magnetic fieldleads to the magnetic field dependence of the attractive interaction.Specifically, the electron density near the surface increases with the magneticfield due to the surface potential well, which causes the reduction in theattractive interaction due to the screening effect. We also develop thecalculation scheme to solve the gap equation of the sc-CDFT with taking intoaccount the magnetic field dependence of the attractive interaction. It isshown that calculation results of the magnetic field dependence of thesuperconducting gap are in good agreement with experimental results of thefirst-order phase transition.
