The effect of lattice strain and antiferromagnetism on superconducting gap in cuprates

The doping of the parent insulating cuprate systems destroys long range antiferromagnetic order and develops superconductivity accompanied by Jahn–Teller type lattice distortion in copper 3d electrons in CuO2 plane. In the present communication, we propose a microscopic model to study the interplay of these long range orders. The superconducting gap (Δ), staggered magnetic field (h) and lattice strain (e) are calculated from the Green’s functions and solved self-consistently for different sets of model parameters of the system. Finally the temperature dependent density of states helps to calculate the magnitudes of the order parameters.
