Comment on: “Quantum dynamics of spin-0 particles in a cosmological space-time”
Year: 2025
Type: letter
Abstract: We analyse a recent paper devoted to the investigation of “the impact of cosmological constant on relativistic quantum systems comprising spin-0 scalar particles”. We show that the authors simplified the radial eigenvalue equations with approximations valid for r ≪ 1 but solved the resulting simplified eigenvalue equations with boundary conditions for large r in one case and r → ∞ in the other. We point out that the exact and approximate solutions for one of the models do not agree and show how to overcome the inconsistence.
