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.

In addition, the London theory can be viewed as a limit (the London limit) of the phenomenological Ginzburg-Landau theory, which in the case of curved space-time is extended with an extra term encoding the interaction with the geometric field, besides the standard extension of the covariant derivatives, to include the Christoffel symbols [35, 36].

The investigation of quark-hadron phase transition in the mentioned interactions in the framework of Ginzburg-Landau theory are also presented.
In [2], to describe the critical phenomena near the transition point, the authors consider two thermo-dynamically distinct phases and suggest the fractional Ginzburg-Landau theory in two interconnected ways.
Building on the Ginzburg-Landau theory, Abrikosov in 1957 proposed that only small regions of such materials--those around which electrons swirl in tiny vortices--lose superconductivity; the bulk of the material remains superconductive.

According to the Ginzburg-Landau theory, a rotating disk of type II superconductor at the phase transition with low temperature (e.g., 70K) generates a scalar field [19-20, 24-30] that varies the equivalent gravitational constant along with the Earth scalar field in and around the superconductor and thus shields the gravitational field of the Earth.
As a consequence, we have analytically studied the gravitational field shielding by scalar field and type II superconductors, in accord with the 5D fully covariant K-K theory with a scalar field and the Ginzburg-Landau theory for superconductors.
Furthermore, there are other articles mentioning theoretical link between the close-packed model and Ginzburg-Landau theory. There is also link between Yang-Baxter theory and Ginzburg-Landau theory [6].
