Quantum Dynamics of Scalar Particles in a Spinning Cosmic String Background with Topological Defects: A Feshbach-Villars Formalism Perspective

Sarra Garah, Abdelmalek Boumali

We study the relativistic quantum dynamics of spin-0 particles in the spacetime of a spinning cosmic string that carries both spacelike disclination (conical deficit $\alpha$) and screw…
