In ultrathin films of FeSe grown on SrTiO3 (FeSe/STO), the superconducting transition temperature Tc is increased by almost an order of magnitude, raising questions on the pairing mechanism. As in other superconductors, antiferromagnetic spin fluctuations have been proposed to mediate SC making it essential to study the evolution of the spin dynamics of FeSe from the bulk to the ultrathin limit. Here, we investigate the spin excitations in bulk and monolayer FeSe/STO using resonant inelastic x… 
Superconductivity in the bilayer Hubbard model: Two Fermi surfaces are better than one
Fully occupied or unoccupied bands in a solid are often considered inert and irrelevant to a material’s low-energy properties. But the discovery of enhanced superconductivity in heavily
A perspective on surface-adsorbed single atom magnets as atomic-scale magnetic memory
Downscaling single magnetic bits to the ultimate size of individual atoms would open the possibility to maximize the magnetic storage density on a solid surface. However, realizing stable magnets of

High temperature superconductivity at FeSe/LaFeO3 interface
TLDR
A new high-Tg interface is constructed, single-layer FeSe interfaced with FeOx-terminated LaFeO3, showing that the cooperative pairing mechanism works beyond FeSe-TiOx, and pointing out a workable route in designing new interfaces to achieve higher Tg.
High-temperature superconductivity and its robustness against magnetic polarization in monolayer FeSe on EuTiO3
Spin degree of freedom generally plays an important role in unconventional superconductivity. In many of the iron-based compounds, superconductivity is found in close proximity to long-range
Pairing enhanced by local orbital fluctuations in a model for monolayer FeSe
The pairing mechanism in different classes of correlated materials, including iron based superconductors, is still under debate. For FeSe monolayers, uniform nematic fluctuations have been shown in a

Anisotropic spin fluctuations in detwinned FeSe
TLDR
Inelastic neutron scattering on a mosaic of single crystals of FeSe is used to demonstrate that spin excitations are most intense at the antiferromagnetic wave vectors QAF, consistent with a highly anisotropic superconducting gap driven by spin fluctuations.
Dichotomy of superconductivity between monolayer FeS and FeSe
TLDR
E elucidation of band structure of monolayer FeS on SrTiO3 is reported, enabled by a unique combination of in situ topotactic reaction and molecular-beam epitaxy method, and suggests that the cross-interface electron–phonon coupling enhances Tc only when it cooperates with the pairing interaction inherent to the superconducting layer.
