Query: Fermi surface topology of LaFePO and LiFeP   We perform charge self-consistent LDA+DMFT (density functional theory
combined with dynamical mean field theory) calculations to study correlation
effects on the Fermi surfaces of the iron pnictide superconductors LaFePO and
LiFeP. We find a distinctive change in the topology of the Fermi surface in
both compounds where a hole pocket with Fe dz^2 orbital character changes its
geometry from a closed shape in LDA to an open shape upon inclusion of
correlations.
