On the Duffin-Kemmer-Petiau equation with linear potential in the presence of a minimal length

We point out an erroneous handling in the literature regarding solutions of the (1+1)-dimensional Duffin-Kemmer-Petiau equation with linear potentials in the context of quantum mechanics with minimal length. Furthermore, using Brau's approach, we present a perturbative treatment of the effect of the minimal length on bound-state solutions when a Lorentz-scalar linear potential is applied.
