Abstract : We briefly review previous measurements of potential differences in nonequilibrium superconductors and describe how the differential resistance of current-induced phase-slip centers in superconducting filaments can be used to infer the transverse-mode branch-imbalance relaxation time. We then report our recent measurements of the magnetic field dependence of this relaxation time, which is found to be in good agreement with the prediction by Schmid and Schön.
