Homes's law

In superconductivity, Homes's law states that a superconductor's transition temperature is proportional to the strength of the superconducting state at zero temperature (that is, the superfluid density) multiplied by the above-transition electrical resistivity. The law is named for physicist Christopher Homes and was first presented in the July 29 2004 edition of Nature.

Homes's law predicts that copper oxide superconductors have high transition temperatures because their above-transition resisitivity is high.

Francis Pratt and Stephen Blundell have shown that Homes's law is violated in the organic superconductors. This work was first presented in Physical Review Letters in March 2005.
