Theory of fluctuation conductivity from interband pairing in pnictide superconductors
arXiv:0902.0303 · doi:10.1103/PhysRevB.79.172508
Abstract
We derive the effective action for superconducting fluctuations in a four-band model for pnictides, discussing the emergence of a single critical mode out of a dominant interband pairing mechanism. We then apply our model to calculate the paraconductivity in two-dimensional and layered three-dimensional systems, and compare our results with recent resistivity measurements in SmFeAsOF
