Abstract

We propose a nonlocal extension of the generalized Dirac oscillator (GDO) in (1+1) dimensions by replacing the multiplicative interaction f(x) with an integral operator hat F with kernel f(x,x'). The resulting Dirac equation preserves an operator factorization and decouples into two nonlocal Schrödinger-type (Sturm--Liouville) equations for the spinor components. We derive explicit expressions for the associated supersymmetric partner kernels in terms of f and its derivatives, and we show that a complex-translation metric η=e-θpx leads to a simple sufficient kernel-level pseudo-Hermiticity constraint, f\(x+iihbarθ,x'+iihbarθ\)=f^*(x',x), extending the familiar local complex-shift criteria. To provide a transparent nonlocal-to-local interpretation, we adapt the Coz--Arnold--MacKellar current-based localization to each component equation, obtaining energy-dependent equivalent local potentials and multiplicative Perey (damping) factors. The mapping breaks down precisely at current zeros, thereby diagnosing the spurious solutions of the corresponding nonlocal Schrödinger problem. Finally, we illustrate the formalism with analytically tractable benchmarks (the local Dirac oscillator and a translation-invariant kernel) and with a finite-rank separable model (Gaussian form factor) that reduces the integro-differential problem to a small set of coupled ordinary differential equations and algebraic constraints.
