Abstract Multi-gap models of high temperature ceramic superconductors have been of considerable recent interest. For the case of a two-gap model (Δ1, and Δ2), there exist two separate electron pair condensate reservoirs, and a bulk Josephson free energy can be associated with electron pair transitions from one reservoir to the other. Thus, a “Josephson effect” can exist in two-gap models without the requirement of a weak link separating the two electron pair reservoirs in space. A single bulk sample Josephson electron pair free energy is here derived from the conventional BCS model of the superconducting state.
