In this work, we use the extended-DMFT (EDMFT) method so that inter-unit-cell correlation effects are taken into consideration. We solve the EDMFT equations with a continuous time quantum Monte Carlo method. An OSMP develops in the presence of the inter-unit-cell spin correlation, through a mechanism suggested by a recent renormalization-group analysis [5]. Implications of our results for the overall physics of iron-based superconductors are discussed.
