# Josephson phase

In superconductivity, the Josephson phase is the difference of the phases of the quantum mechanical wave function in two superconducting electrodes forming a Josephson junction.

$\Psi_1 = \sqrt{n_s} e^{i\theta_1}$ $\Psi_2 = \sqrt{n_s} e^{i\theta_2}$
then the Josephson phase is $\phi\ \stackrel{\mathrm{def}}{=}\ \theta_2-\theta_1$.
