The nature and origin of electronic nematicity remains a significant challenge in our
understanding of the iron-based superconductors. This is particularly evident in the iron …

Uniaxial stress has proven to be a powerful experimental tuning parameter for effectively
controlling lattice, charge, orbital, and spin degrees of freedom in quantum materials. In …

The attractive interaction in conventional BCS superconductors is provided by a bosonic
mode. However, the pairing glue of most unconventional superconductors is unknown. The …

The interfacial FeSe/TiO2− δ coupling induces high-temperature superconductivity in
monolayer FeSe films. Using cryogenic atomically resolved scanning tunneling microscopy …

We study the crystal structure of the tetragonal iron selenide FeSe and its nematic phase
transition to the low-temperature orthorhombic structure using synchrotron x-ray and neutron …

We calculated the structural, electronic, and magnetic properties of FeSe within density-
functional theory at the generalized gradient approximation level. First, we studied how the …

We show, by means of dynamical mean-field theory calculations, that the experimental
fingerprints of the nematic order in iron-based superconductors are intrinsically connected …

Nematicity, which refers to a phase of broken rotational but preserved translational
symmetry, is underlined by the appearance of anisotropic properties and leaves remarkable …

We analyze theoretically the magnetic anisotropy in the nematic phase of FeSe by
computing the spin and the orbital susceptibilities from the microscopic multiorbital model. In …
