Abstract. Based on the consideration given by the Ginzburg-Landau (GL) theory
according to the variational principle, we assume that the microscopic Gibbs function
density given by [1] must be stationary at the
thermodynamical equilibrium. To describe the universal propagation of the order
parameter, we express order phases and amplitudes as dealing with tensor elements. In
addition to the variation of the order parameter and the vector potential limited by the
condition A (x) B(x) r r r ∇ × = , we introduce here the concept of elasticity to describe the
propagation of the superconducting state as “the little waves borning on smooth
Superconductor Sea [2]”. The coherence concept transits to the asymptotic behaviour, we
shall say that equivalence concept is its limit, this must transgress the propagation laws
of superconductivity to be replaced by the increasing of superconductivity.
Superconductivity will be viewed as second order extensive value, propagation seems to
be so quick to avoid the stability, the increasing of superconductivity requires more time,
and more time will be equivalent to a second and added measurement process
eliminating the degeneracy of the first integral during the cooling process. It may deal
with the first approximated stability of Superconductor State. The uncertainly in quantum
mechanics is limited as scale length relations for the dimension coherence of the order
parameter and temperatures.
Keywords: superconductivity, order parameter, elasticity.
