Abstract
We report a variational Monte Carlo (VMC) study of the iron-based superconductors. We use realistic band structures, and the ordering instabilities/variational ansatz 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.
