Fe-based superconductors bridge a gap between MgB 2 and the cuprate high temperature
superconductors as they exhibit multiband character and transition temperatures up to …

The puzzling nature of magnetic and lattice phase transitions of iron pnictides is investigated
via a first-principles Wannier function analysis of representative parent compound LaOFeAs …

The theoretical need to study the properties of the Fe-based high-T c superconductors using
reliable many-body techniques has highlighted the importance of determining what is the …

We use high-resolution angle-resolved photoemission to study the electronic structure of the
BaFe 2 As 2 pnictides. We observe two electron bands and two hole bands near the X …

A recently proposed two-orbital model for the Fe-based superconductors is studied using the
Lanczos method on small clusters as well as pairing mean-field approximations. Our main …

The interplay between the structural and magnetic phase transitions occurring in the Fe-
based pnictide superconductors is studied within a Ginzburg-Landau approach. We show …

The results of neutron-scattering and angle-resolved photoemission experiments for the Fe-
pnictide parent compounds, and their metallic nature, are shown to impose severe …

The fascination of mankind towards a sudden change of a property, like colour, shape,
elasticity, viscosity, electrical conductivity and magnetism, is well known. If the change in …

Multiorbital Hubbard model Hamiltonians for the undoped parent compounds of the Fe-
pnictide superconductors are investigated here using mean-field techniques. For a realistic …

We propose a five-band tight-binding model for the Fe-As layers of iron pnictides with the
hop** amplitudes calculated within the Slater-Koster framework. The band structure found …
