Superfluid flow in disordered superconductors with Dynes pair-breaking scattering: Depairing current, kinetic inductance, and superheating field

T Kubo - Physical Review Research, 2020 - APS
We investigate the effects of Dynes pair-breaking scattering rate Γ on the superfluid flow in a
narrow thin-film superconductor and a semi-infinite superconductor by self-consistently
solving the coupled Maxwell and Usadel equations for the BCS theory in the diffusive limit
for all temperature T, all Γ, and all superfluid momentums. We obtain the depairing current
density jd (Γ, T) and the current-dependent nonlinear kinetic inductance L k (js, Γ, T) in a
narrow thin film and the superheating field H sh (Γ, T) and the current distribution in a semi …

Additionally, two lines below Eq.(58), it should state Csm= 3Cfm. Equation (C9) also
contains a typographical error. The second term in the parentheses of the numerator is
written as 8/π in the published version, but it should be π/8. The correct equation is α= 1+
π/2− 2 (1+ π/8) ζd0 2+ 3π2/8− πζd0= 0. 365.
