A First-Order Phase Transition in Spin-Imbalanced BCS Theory of Superconductivity

Marius Lemm, Barbara Roos

We study a translation-invariant BCS functional of superconductivity for a system of spin- $1/2$ fermions with spin-dependent chemical potentials, $μ_{+} \neq = μ_{-}$ . Numerical work of Ca…

Linear Criterion for an Upper Bound on the Bardeen-Cooper-Schrieffer Critical Temperature

Barbara Roos

Since Bardeen-Cooper-Schrieffer theory of superconductivity is non-linear, it is difficult to study superconducting properties analytically. There is a more tractable linear criter…
