Superconductivity is a remarkably widespread phenomenon that is observed in most metals
cooled to very low temperatures. The ubiquity of such conventional superconductors, and …

Emergent electronic phenomena in iron-based superconductors have been at the forefront
of condensed matter physics for more than a decade. Much has been learned about the …

The superconductor iron selenide (FeSe) is of intense interest owing to its unusual
nonmagnetic nematic state and potential for high-temperature superconductivity. But its …

The recently discovered Fe-pnictide and chalcogenide superconductors display low-
temperature properties suggesting superconducting gap structures which appear to vary …

We demonstrate, using first-principles calculations, that the electronic structure of FeSe 1− x
Te x (x= 0.5) is topologically nontrivial and characterized by an odd Z 2 invariant and Dirac …

Strong electronic correlations are often associated with the proximity of a Mott-insulating
state. In recent years however, it has become increasingly clear that the Hund's rule …

The iron pnictide and chalcogenide compounds are a subject of intensive investigations
owing to their surprisingly high temperature superconductivity. They all share the same …

We show that electron-and hole-doped BaFe 2 As 2 are strongly influenced by a Mott
insulator that would be realized for half-filled conduction bands. Experiments show that …

Iron-based superconductors are well known for their complex interplay between structure,
magnetism and superconductivity. FeSe offers a particularly fascinating example. This …

In this work, we address the question of calculating the local effective Coulomb interaction
matrix in materials with strong electronic Coulomb interactions from first-principles. To this …
