= |Ψ|e^(iφ), where |Ψ| is the amplitude of the order parameter and φ is the phase. The quantization of magnetic flux in a superconductor leads to the following relation: where Φ is the magnetic flux, A is the vector potential, dl is an infinitesimal element along the closed loop, n is an integer, h
