Spatial correlation of fluctuations in multi-component superconducting systems
arXiv:1211.5287
Abstract
We show that spatial variation and correlation of superconductivity fluctuations in a two-band model are scaled by two characteristic lengths. This results in substantially more complicated picture compared to one-band systems. In particular, short-range correlations are always present in a two-band scenario, even near the phase transition point.
