Ginzburg-Landau theory

[′ginz·bərg ′lan·dau̇ ‚thē·ə·rē]
(cryogenics)
A phenomenological theory of superconductivity which accounts for the coherence length; the ordered state of a superconductor is described by a complex order parameter which is similar to a Schrödinger wave function, but describes all the condensed superelectrons, rather than a single charged particle. Also known as Landau-Ginzburg theory.
