ABSTRACT
A mean-field treatment is presented of a square lattice two-orbital-model for [Formula see text] taking into account intra- and inter-orbital superconductivity. A rich phase diagram involving both types of superconductivity is presented as a function of the ratio between the couplings of electrons in the same and different orbitals ([Formula see text]) and electron doping x. With the help of a quantity we call orbital-mixing ratio, denoted as [Formula see text], the phase diagram is analyzed using a simple and intuitive picture based on how [Formula see text] varies as electron doping increases. The predictive power of [Formula see text] suggests that it could be a useful tool in qualitatively (or even semi-quantitatively) analyzing multiband superconductivity in BCS-like superconductors.
