Group theory of Wannier functions providing the basis for a deeper understanding of magnetism and superconductivity
Ekkehard Krüger, Horst P. Strunk
The paper presents the group theory of best localized and symmetry-adapted Wannier functions in a crystal of any given space group G or magnetic group M. Provided that the calculat…
Structural distortion in antiferromagnetic BaFe2As2 as a result of time-inversion symmetry
Ekkehard Krüger, Horst P. Strunk
As reported by Q. Huang et al. [Phys. Rev. Lett. 101, 257003 (2008)], neutron diffraction studies show an onset of antiferromagnetic order in BaFe2As2 associated with a tetragonal-…
Structural distortion as prerequisite for superconductivity in LiFeAs
Ekkehard Krüger, Horst P. Strunk
The nonadiabatic Heisenberg model predicts a structural distortion in LiFeAs below a temperature higher than (or at least equal to) the superconducting transition temperature. With…
The reason why doping causes superconductivity in LaFeAsO
Ekkehard Krüger, Horst P. Strunk
The experimental observation of superconductivity in LaFeAsO appearing on doping is analyzed with the group-theoretical approach that evidently led in a foregoing paper (J. Superco…
The structural distortion in antiferromagnetic LaFeAsO investigated by a group-theoretical approach
Ekkehard Krüger, Horst P. Strunk
As experimentally well established, undoped LaFeAsO is antiferromagnetic below 137K with the magnetic moments lying on the Fe sites. We determine the orthorhombic body-centered gro…
