The importance of
order
Together
with his colleague Lev Landau, Vitaly Ginzburg
developed a phenomenological theory of
superconductivity in the late 1940s. This theory
proposes that those electrons that contribute to
superconduction form a superfluid. The superconductor
is described by a complex function called the order parameter, and
indicates the fraction of electrons that has
condensed into a superfluid.


The
GinzburgLandau order parameter
is the solution of an equation similar to
the quantummechanical wave
equation.
