The superconductivity in iron based superconductors is hotly discussed since its discovery. The pairing mechanism and the gap structures for such superconductors are the core of attraction for debate. The superconductivity exists on the suppression of the pseudo gaps like antiferromagnetism and structural distortion. The Fermi surface band structure is studied by proposing a tight binding two-orbital model in s ± -wave pairing symmetry for the coexistence of Jahn-Teller distortion and antiferromagnetism with superconductivity.
