Quantum Dynamics of a Scalar Particle in Schwarzschild Spacetime using the Generalized Feshbach Villars Transformation

Sarra Garah, Abdelmalek Boumali

In this work, we apply the generalised Feshbach Villars transformation (GFVT) to spin-0 scalar fields in a Schwarzschild gravitational background. Starting from the covariant Klein…
