Theoretical study of impurity-induced magnetism in FeSe
Johannes H. J. Martiny, Andreas Kreisel, Brian M. Andersen
Experimental evidence suggests that FeSe is close to a magnetic instability, and recent scanning tunneling microscopy (STM) measurements on FeSe multilayer films have revealed stri…
Spin Waves in Detwinned BaFeAs
Xingye Lu, Daniel D. Scherer, David W. Tam +8
Understanding magnetic interactions in the parent compounds of high-temperature superconductors forms the basis for determining their role for the mechanism of superconductivity. F…
Itinerant approach to magnetic neutron scattering of FeSe: effect of orbital selectivity
Andreas Kreisel, Brian M. Andersen, P. J. Hirschfeld
Recent STM experiments and theoretical considerations have highlighted the role of interaction-driven orbital selectivity in FeSe, and its role in generating the extremely anisotro…
Suppression of superfluid stiffness near Lifshitz-point instability to finite momentum superconductivity
Jonatan Wårdh, Mats Granath, Brian M. Andersen
We derive the effective Ginzburg-Landau theory for finite momentum (FFLO/PDW) superconductivity without spin population imbalance from a model with local attraction and repulsive p…
Imaging Orbital-selective Quasiparticles in the Hund's Metal State of FeSe
Andrey Kostin, Peter O. Sprau, Andreas Kreisel +6
Strong electronic correlations, emerging from the parent Mott insulator phase, are key to copper-based high temperature superconductivity (HTS). By contrast, the parent phase of ir…
