Superconductivity develops in metals upon the formation of a coherent macroscopic
quantum state of electron pairs. Iron pnictides and chalcogenides are materials that have …

The Majorana fermion, which is its own antiparticle and obeys non-Abelian statistics, plays a
critical role in topological quantum computing. It can be realized as a bound state at zero …

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

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 …

Motivated by the recent discovery of superconductivity in La 3 Ni 2 O 7 under pressure, we
discuss the basic ingredients of a model that captures its microscopic physics under …

FeSe is a fascinating superconducting material at the frontier of research in condensed
matter physics. Here, we provide an overview of the current understanding of the electronic …

Almost a decade has passed since the serendipitous discovery of the iron-based high
temperature superconductors (FeSCs) in 2008. The fact that, as in the copper oxide high …

Superconductivity emerges in proximity to a nematic phase in most iron-based
superconductors. It is therefore important to understand the impact of nematicity on the …

Electronic correlation is of fundamental importance to high temperature superconductivity.
While the low energy electronic states in cuprates are dominantly affected by correlation …
