FeSe is a fascinating superconducting material at the frontier of research in condensed
matter physics. Here, we provide an overview of the current understanding of the electronic …

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

High-temperature superconductivity in iron pnictides and chalcogenides emerges when a
magnetic phase is suppressed. The multi-orbital character and the strength of correlations …

We have observed Shubnikov–de Haas oscillations in FeSe. The Fermi surface deviates
significantly from predictions of band-structure calculations and most likely consists of one …

We construct the symmetry adapted low-energy effective Hamiltonian for the electronic
states in the vicinity of the Fermi level in iron-based superconductors. We use Luttinger's …

The in-plane resistivity anisotropy is studied in strain-detwinned single crystals of FeSe. In
contrast to other iron-based superconductors, FeSe does not develop long-range magnetic …

The superconductivity discovered in iron pnictides is intimately related to a nematic ground
state, where the C 4 rotational symmetry is broken via the structural and magnetic …

Unconventional superconductivity usually originates from several strongly coupled degrees
of freedom, such as magnetic, charge and elastic. A highly anisotropic electronic phase, not …

The nature of the pseudogap (PG) in high transition temperature (high T c) superconducting
cuprates has been a major issue in condensed matter physics. It is still unclear whether the …

We investigated the in-plane resistivity anisotropy for underdoped Ba (Fe 1-x Co x) 2 As 2
single crystals with improved quality. We demonstrate that the anisotropy in resistivity in the …
