Impurity bound states and disorder-induced orbital and magnetic order in the s+- state of Fe-based superconductors
Maria N. Gastiasoro, Brian M. Andersen
We study the presence of impurity bound states within a five-band Hubbard model relevant to iron-based superconductors. In agreement with earlier studies, we find that in the absen…
Impurity states and cooperative magnetic order in Fe-based superconductors
Maria N. Gastiasoro, P. J. Hirschfeld, Brian M. Andersen
We study impurity bound states and impurity-induced order in the superconducting state of LiFeAs within a realistic five-band model based on the band structure and impurity potenti…
Impurity-induced sub-gap bound gap states in alkali doped iron chalcogenide superconductors
Shantanu Mukherjee, Maria N. Gastiasoro, Brian M. Andersen
Measurements of the local density of states near impurities can be useful for identifying the superconducting gap structure in alkali doped iron chalcogenide superconductors K_xFe_…
Origin of electronic dimers in the spin-density wave phase of Fe-based superconductors
Maria N. Gastiasoro, P. J. Hirschfeld, Brian M. Andersen
We investigate the emergent impurity-induced states arising from point-like scatterers in the spin-density wave phase of iron-based superconductors within a microscopic five-band m…
Low-energy bound states at interfaces between superconducting and block antiferromagnet regions in KxFe{2-y}Se2
S. Mukherjee, M. N. Gastiasoro, P. J. Hirschfeld +1
The high-Tc alkali doped iron selenide superconductors KxFe{2-y}Se2 have been recently shown to be intrinsically phase separated into Fe vacancy ordered block antiferromagnetic reg…
