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 …

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 …

FeSe is an intriguing iron-based superconductor. It presents an unusual nematic state
without magnetism and can be tuned to increase the critical superconducting temperature …

The FeSe nematic phase has been the focus of recent research on iron-based
superconductors (IBSs) due to its unusual properties, which are distinct from those of the …

Starting from a low-energy continuum model for the band dispersion of the 2× 2 charge-
ordered phase of the kagome metals AV 3 Sb 5 (A= K, Rb, Cs), we show that nematicity can …

Electronic nematic behavior has been identified and studied in iron-based superconductors
for some time, particularly in the well-known BaFe 2 As 2 system, where it is well known to …

FeSe is arguably the simplest, yet the most enigmatic, iron-based superconductor. Its
nematic but non-magnetic ground state is unprecedented in this class of materials and …

Recent STM experiments and theoretical considerations have highlighted the role of
interaction-driven orbital selectivity in FeSe, and its role in generating the extremely …

We report the evolution of the electronic nematic susceptibility in FeSe via Raman scattering
as a function of hydrostatic pressure up to 5.8 GPa where the superconducting transition …
