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

The recent discovery of superconductivity in La 3 Ni 2 O 7 with T c≃ 80 K under high
pressure opens up a new route to high-T c superconductivity. This material realizes a bilayer …

We review two important non-perturbative approaches for extracting the physics of low-
dimensional strongly correlated quantum systems. Firstly, we start by providing a …

We present a comprehensive study of the evolution of the nematic electronic structure of
FeSe using high-resolution angle-resolved photoemission spectroscopy (ARPES), quantum …

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 …

Establishing the appropriate theoretical framework for unconventional superconductivity in
the iron-based materials requires correct understanding of both the electron correlation …

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

Using resistivity, heat-capacity, thermal-expansion, and susceptibility measurements we
study the normal-state behavior of KFe 2 As 2. Both the Sommerfeld coefficient (γ≈ 103 mJ …

Magnetic kagome materials provide a fascinating playground for exploring the interplay of
magnetism, correlation and topology. Many magnetic kagome systems have been reported …

The symmetry of the wavefunction describing the Cooper pairs is one of the most
fundamental quantities in a superconductor, but for iron-based superconductors it has …
