NettetFurthermore, BCS theory has proven unable to predict any new superconducting compounds. This paper suggests the possibility that BCS theory itself as the theory of ‘conventional’ superconductivity may require a fundamental overhaul.

One of the prominent LM results is that the T = 0 superﬂuid density ρ s0 coincides with total density ρ, irrespective of the strength of interparticle forces. However, the LM theory fails to describe supercon-ducting alloys.
