We report a series of calculations testing the predictions of the Tran-Blaha functional for the
electronic structure and magnetic properties of condensed systems. We find a general …

In correlated metals derived from Mott insulators, the motion of an electron is impeded by
Coulomb repulsion due to other electrons. This phenomenon causes a substantial reduction …

We review the main ingredients for an unconventional pairing state in the ferropnictides, with
particular emphasis on interband pairing due to magnetic fluctuations. Summarizing the key …

The term'high-temperature superconductor'used to refer only to copper-based compounds—
now, iron-based pnictides have entered the frame. The comparison of these two types of …

Effective low-energy Hamiltonians for several different families of iron-based
superconductors are compared after deriving them from the downfolding scheme based on …

Establishing the appropriate theoretical framework for unconventional superconductivity in
the iron-based materials requires correct understanding of both the electron correlation …
