Abstract

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 CuO 2 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.
