- The antinodal pseudogap is a result of an incommensurate SDW.
[PRB 2009,

- Main contribution to both the electron scattering and superconducting pairing comes from the spin-fluctuations.

Iron based superconductors (FeSC)
[LTP 2012]
- The band structure, in terms of number and symmetry of the bands, is well captured by LDA but not the Fermi surface geometry
[PRL 2010]
or even topology.

- Main contributors to superconductivity are Fe 3dxz/yz electrons and maximum of Tc for different compounds correlates with the vicinity of the Van Hove singuliarities for the dxz- and dyz-bands to the Fermi level.
