On the Feshbach-Villars oscillators (FVO) under coulomb potential in the cosmic dislocation space-time

In this paper, we investigate the quantum mechanical dynamics of the massive and relativistic Feshbach-Villars oscillator in cosmic dislocation space-time induced by a coulomb-type potential. The first-order Feshbach-Villars version of the Klein-Gordon equation is used to find movement equations. Wave functions and associated energy have been calculated (both in the free case and in the interaction case). We analyse the impact of dislocation topology on this interaction. As a result, the effect of the dislocation on the quantum system under study is examined.
