Werthamer–Helfand–Hohenberg theory
This theory was proposed in 1966 [1] to go beyond BCS theory of superconductivity and it provides predictions of upper critical field (Hc2) in type-II superconductors [2] .[3] The theory predicts the upper critical field (Hc2) at 0 K from Tc and the slope of Hc2 at Tc.
