In physics, The WerthamerâHelfandâHohenberg (WHH) theory was proposed in 1966 by N. Richard Werthamer, Eugene Helfand and Pierre Hohenberg [1] to go beyond BCS theory of superconductivity and it provides predictions of upper critical field (Hc2) in type-II superconductors. [1] [2] The theory predicts the upper critical field (Hc2) at 0 K from Tc and the slope of Hc2 at Tc.
