摘要：

The creation rate of phase slip vortices is related to an energy barrier through an Arrhenius law. By computing a proportionality factor that relates the Josephson frequency to the Arrhenius rate one can then deduce the form of the vortex nucleation energy barrier from the observed dependence of critical velocity on pressure drive. The results of a numerical simulation is presented which evaluates this factor over a large parameter space.
