Abstract: This is proposed to answer for co-existences superconductivity (SC) in the orbital overlap and magnetism, i.e. antiferromgnetism (AF) in iron based superconductors. This theory shows a gradual transition in the Nambu generalization of the Bardeen Cooper Schrieffer model to the psudospin Hamiltonian representation leading up to SC and AF state.
