Abstract
In this chapter we treat two contrasting examples of the longitudinal mode of quasiparticle disequilibrium. First, we treat the rather classical problem of heating effects in three-dimensional constriction weak links, which increase the Johnson noise, while reducing the critical current and energy gap. Second, we treat the more subtle nonequilibrium effects generated by a time-varying energy gap. These provide a kind of negative feedback effect which slows down the gap response time from τGL to τΔ, which may be orders of magnitude longer, and also provides a type of dynamic enhancement of superconductivity in current-driven metallic weak links.
