LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

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

The surprising discovery of superconductivity in layered iron-based materials, with transition
temperatures climbing as high as 55 K, has led to thousands of publications on this subject …

Whether a quantum critical point (QCP) lies beneath the superconducting dome has been a
long-standing issue that remains unresolved in many classes of unconventional …

In iron pnictides, we find that the moderate electron-phonon interaction due to the Fe-ion
oscillation can induce the critical d-orbital fluctuations, without being prohibited by the …

We study the effect of the lattice structure on the spin-fluctuation-mediated superconductivity
in the iron pnictides adopting the five-band models of several virtual lattice structures of …

The physics of superconductivity in magic-angle twisted bilayer graphene (MATBG) is a
topic of keen interest in moiré systems research, and it may provide an insight into the …

We discuss the basic ideas of relativistic transport models used for the interpretation and
description of experimental data from heavy-ion collisions at high collision energies. We …

I review theoretical ideas and implications of experiments for the gap structure and symmetry
of the Fe-based superconductors. Unlike any other class of unconventional …
