The electronic instabilities of the Iron-based superconductors: a variational Monte-Carlo study
arXiv:1007.2643 · doi:10.1103/PhysRevB.83.134502
Abstract
We report the first variational Monte Carlo (VMC) study of the iron-based superconductors. We use realistic band structures, and the ordering instabilities/variational ansatzs are suggested by previous functional renormalization group calculations. We examine antiferromagnetism, superconducting pairing, normal state fermi surface distortion, and orbital order in the antiferromagnetic state.
