A Diagrammer's Note on Superconducting Fluctuation Transport for Beginners: I. Conductivity and Thermopower
arXiv:1112.1513
Abstract
A diagrammatic approach based on thermal Green function to superconducting fluctuation transport is reviewed keeping consistency with Ginzburg-Landau theory. The correct expression of the heat current vertex for Cooper pairs is clarified via Jonson-Mahan formula and Ward identities.
In v3 two sections have been added: 17. Remarks on Heat Current, 18. Gauge Theory of Heat
