We also include the effect of excitons for which we solve Bethe-Salpeter Equation.
It is well known that the conventional Bethe-Salpeter equation is with difficulties such as the relative time and relative energy problem which leads to the existence of nonphysical solutions in the conventional Bethe-Salpeter equation [7-32].
We see that in this reformulated Bethe-Salpeter equation the relative time and relative energy problem of the conventional Bethe-Salpeter equations is resolved [7-32].
