Competition between superconductivity and nematic order: Anisotropy of superconducting coherence length
Competition between superconductivity and nematic order: Anisotropy of superconducting coherence length
We study the interplay between nematic order and superconductivity, motivated by a recent experiment on FeSe observing strongly distorted vortex shapes (Song et al., Science 332, 1410 (2011)). We show that the nematic order strongly enhances the anisotropy in the superconducting coherence length, beyond that expected from considerations of the …
