Abstract

In this paper we present a description of the Nernst electric field E generated by forced flux tube motion due to a temperature gradient backward differenceT. Depending on the value of backward differenceT with respect to a critical gradient backward differenceTcrit, we find for backward differenceT/backward differenceTcritmuch less-than 1 a regime E ∝ backward differenceT, in close analogy to ...
