Analytical and Numerical Bound-State Analysis of One-Dimensional Time-like Vector Potentials in the Feshbach–Villars Formalism

We analyse one-dimensional bound states of spin-zero particles coupled to external time-like vector potentials within the Feshbach–Villars representation. The study is organised around a practical criterion of physical admissibility that distinguishes genuine bound states from sc...
