GENERALIZED FLUX-QUANTIZATION AND AC JOSEPHSON EFFECT IN A MODEL SUPERCONDUCTOR

Some properties of a model Ginzburg-Landau-like equation extended to i nclude time-dependence and a 4-potential are investigated. Applied ele ctric field in a ''hole'' in the bulk model superconductor oriented in space-time so as to have cross sections in the t-z planes is shown to lead to quantized trapped flux of a new kind, ''electric space-time f lux'' The nontrivial space- and time-dependent solution in the bulk su perconductor is found. Further, the analogue of the ac Josephson effec t follows simply.
