Although the pairing mechanism of Fe-based superconductors (FeSCs) has not yet been
settled with consensus with regard to the pairing symmetry and the superconducting (SC) …

This article reviews theoretical and experimental work on the novel physics in multiband
superconductors. Multiband superconductors are characterized by multiple superconducting …

We show that a two-dimensional semiconductor with Rashba spin-orbit coupling could be
driven into the second-order topological superconducting phase when a mixed-pairing state …

The recent discovery of high-temperature superconductivity in single-layer iron selenide has
generated significant experimental interest for optimizing the superconducting properties of …

Over the past years a lot of theoretical and experimental effort has been made to find states
with broken time-reversal symmetry (BTRS) in multiband superconductors. In particular, it …

A central question in iron-based superconductivity is the mechanism by which the paired
electrons minimize their strong mutual Coulomb repulsion. In most unconventional …

The characteristics of Fe-based superconductors are manifested in their electronic, magnetic
properties, and pairing symmetry of the Cooper pair, but the latter remain to be explored …

We report a sudden reversal in the pressure dependence of T c in the iron-based
superconductor RbFe 2 As 2, at a critical pressure P c= 11 kbar. Combined with our prior …

The origin of high-temperature superconductivity in iron-based superconductors is still not
understood; determination of the pairing symmetry is essential for understanding the …

Using two experimental techniques, we studied single crystals of the 122-FeAs family with
almost the same critical temperature, T c. We investigated the temperature dependence of …
