To accomplish this, we address the relativistic Klein- Gordon wave equation and derive analytical solutions for the quantum system by employing the confluent Heun function. Significantly, our research reveals that the behavior of the scalar fields is notably influenced not only by the cosmic strings and wormhole throat radius but also by the parameter of rainbow gravity.eninfo:eu-repo/semantics/closedAccessModified Theories of GravityLinear DefectsDisclinationsQuantum Field in Curved Space-TimeRelativistic Wave EquationSolutions of Wave EquationsSpecial FunctionsArticle
