Testing the sign-changing superconducting gap in iron-based superconductors with quasiparticle interference and neutron scattering
Tanmoy Das, A. V. Balatsky
We present a phenomenological calculation of the quasiparticle-interference (QPI) pattern and inelastic Neutron scattering (INS) spectra in iron-pnictide and layered iron-selenide…
Imaging spin-inelastic Friedel oscillations emerging from magnetic impurities
J. Fransson, A. V. Balatsky
We consider inelastic scattering of localized magnetic moments coupled with the electrons on the surface. We argue that spin-inelastic transitions of the magnetic impurities genera…
Modulated superconductivity due to vacancy and magnetic order in FeSe [Cs, K, (Tl,Rb), (Tl,K)] iron-selenide superconductors
Tanmoy Das, A. V. Balatsky
We present a calculation of a 'modulated' superconducting state in iron-selenide superconductors. The zero-momentum wave pairing breaks the translational symmetry of the conven…
Induced polarization at a paraelectric/superconducting interface
J. T. Haraldsen, S. A. Trugman, A. V. Balatsky
We examine the modified electronic states at the interface between superconducting and ferro(para)-electric heterostructures. We find that electric polarization and superconduc…
