Soliton-like Solutions of the Complex Non-linear Klein-Gordon Systems in 1 + 1 Dimensions

In this paper, we present soliton-like solutions of the non-linear complex klein-gordon systems in 1 + 1 dimensions. we will use polar representation to introduce three different soliton-like solutions including, complex kinks (anti-kinks), radiativeprofiles, and localized wave-packets. complex kinks (anti-kinks) are topological objects with zero electrical charges. radiative profiles are objects that move at the speed of light and therefore, have a zero rest mass. they can be created in kink-anti-kink collisions and vice versa. localized wave packet solutions are non-topological objects for which wave and particle behavior are reconciled in a classical way. for localized wave packet solutions, the trivial initial phase imposes an uncertainty on the collision fates.
