Abstract:We study a fermion-boson transformation. Our approach is based on the 3 × 3 equations which are subequations of both the Dirac and Duffin-Kemmer-Petiau equations and thus provide a link between these equations. We show that solutions of the free Dirac equation can be converted to solutions of spin-0 Duffin-Kemmer-Petiau equation and vice versa. Mechanism of this transition assumes existence of a constant spinor.
“…In the present paper we generalize results of [9] in two directions. Firstly, we generalize the fermion-boson transformation connecting solutions of free Dirac and spin-0 DKP equations in presence of Weyl spinor.…”

“…Recently, the smooth and controlled evolution from a fermionic Bardeen-Cooper-Schrieffer (BCS) superfluid state to a molecular Bose-Einstein condensate (BEC) has been realized in ultracold Fermi gases [11]. On the other hand, we have shown recently that solutions of the Dirac equation can be transformed in the non-interacting case, assuming existence of a constant spinor, to solutions of the spin-0 Duffin-Kemmer-Petiau (DKP) equation and vice versa [9]. Possible analogy between BCS-BEC transition and our findings is motivation of our work.…”

We study fermion-boson transitions. Our approach is based on the 3 × 3 subequations of Dirac and Duffin-Kemmer-Petiau equations, which link these equations. We demonstrate that free Dirac equation can be invertibly converted to spin-0 Duffin-Kemmer-Petiau equation in presence of a neutrino field. We also show that in special external fields, upon assuming again existence of a neutrino (Weyl) spinor, the Dirac equation can be transformed reversibly to spin-0 Duffin-Kemmer-Petiau equation. We argue that such boson-fermions transitions are consistent with the main channel of pion decay.

“…On the other hand, these solutions do not contain all spinor components and are thus noncovariant solutions of covariant equations. We studied this problem in [23,24]. In the present work, we show that, in the free case, full covariant solutions of the = 0 and = 1 DKP equations are generalized solutions of the Dirac equation.…”
We study internal structure of the Duffin-Kemmer-Petiau equations for spin 0 and spin 1 mesons. We show that in the noninteracting case full covariant solutions of thes=0ands=1DKP equations are generalized solutions of the Dirac equation.
