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 …

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

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

High-temperature superconductivity and a wide variety of exotic superconducting states
discovered in FeSe-based materials have been at the frontier of research on condensed …

We discuss the influence on spin-fluctuation pairing theory of orbital selective strong
correlation effects in Fe-based superconductors, particularly Fe chalcogenide systems. We …

The iron-based superconductors are characterized by multiple-orbital physics where all the
five Fe 3 d orbitals get involved. The multiple-orbital nature gives rise to various novel …

Isoelectronic substitution is an ideal tuning parameter to alter electronic states and
correlations in iron-based superconductors. As this substitution takes place outside the …

The structure of the superconducting gap in unconventional superconductors holds a key to
understand the momentum-dependent pairing interactions. In superconducting FeSe, there …

We present a systematic angle-resolved photoemission spectroscopy study of the
superconducting gap in FeSe. The gap function is determined in a full Brillouin zone …

PdTe is a superconductor with T c~ 4.25 K. Recently, evidence for bulk-nodal and surface-
nodeless gap features has been reported in PdTe. Here, we investigate the physical …
