Physical Review B 85(18): 184511.1098-0121http://nrs.harvard.edu/urn-3:HUL.InstRepos:10860095We 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 Ginzburg-Landau theory. We obtain universal functions describing the coupling between the nematic order and superconductivity, and discuss connections of our results to the experiments.en-USstrongly correlated electronsJournal Article2013-07-0510.1103/PhysRevB.85.184511
