Symbol: ξ
Definition: length describing the spatial variation of the order parameter in the Ginzburg-Landau theory

Note 1 to entry: ξ called the Ginzburg-Landau coherence length is a function of temperature and nearly equal to the BCS coherence length, ξ0, at 0 K in a clean superconductor (815-10-35).

Note 2 to entry: ξ = (Φ0/2πμ0Hc2)1/2, where Φ0 is the flux quantum, μ0 is the magnetic constant and Hc2 is the upper critical field strength.
