BCS theory: see superconductivitysuperconductivity,
abnormally high electrical conductivity of certain substances. The phenomenon was discovered in 1911 by Heike Kamerlingh Onnes, who found that the resistance of mercury dropped suddenly to zero at a temperature of about 4.

As is known, in BCS theory
, a jump in the heat capacity is equal to
Therefore, one may say that the most distinctive aspect between geometrization program to describe hadron models and the composite models (especially Nambu's BCS theory
), is that the first approach emphasizes its theoretical correspondence to the General Relativity, metric tensors etc., while the latter emphasizes analogies between hadron physics and the strong field of superconductors .
As a result, BCS Theory
, which had served as the standard model for describing superconductivity for decades, was simply not adequate to describe it.

of nodal superconductors, highly correlated particle systems and the composite operator method, diagonalization- and numerical renormalization-group-based methods for interacting quantum systems, and unconventional superconductivity.
