Effect of spin fluctuations on Tc from density-functional theory for superconductors

Abstract

The transverse spin fluctuations are introduced to the density functional theory for superconductors (SCDFT). Paramagnons are treated within the random phase approximation and assumed to be the same for the normal and superconducting state. The effect of spin fluctuations on Tc is studied for a few simple metals at ambient pressure and niobium at several pressures up to 80 GPa.
