Nonlocal correlations in the vicinity of the $\alpha$-$\gamma$ phase transition in iron within a DMFT plus spin-fermion model approach

A. A. Katanin, A. S. Belozerov, V. I. Anisimov

We consider nonlocal correlations in iron in the vicinity of the $\alpha$-$\gamma$ phase transition within the spin-rotationally-invariant dynamical mean-field theory (DMFT) approach, combin…
