It is shown that below the threshold of pair creation, a consistent quantum mechanical
interpretation of relativistic spin-0 and spin-1 particles (both massive and mussless) is …

The uniqueness of the Bohmian particle interpretation of the Kemmer equation, which
describes massive spin-0 and spin-1 particles, is discussed. Recently the same problem for …

We show that it is possible to use the Klein-Gordon, Proca and Maxwell formulations to
construct multi-component relativistic configuration space wavefunctions of spin-0 and spin …

A single-particle quantum formalism is constructed for spin-zero particles based upon state
functions and operators defined on a four-dimensional space-time manifold. This yields a …

It is generally believed that the de Broglie-Bohm model does not admit a particle
interpretation for massive relativistic spin-0 particles, on the basis that particle trajectories …

Guided by a diagonalized form of the classical field-energy we construct a time-dependent
canonical pair of Schrödinger fields Φ t (x) and Π t (x) which diagonalizes the field …

This paper discusses four related topics of the theory of relativistic free particle equations. 1.
I. A unified equation is derived for the Zitterbewegung of the space coordinate. Our …

The nonrelativistic limit of the linear wave equation for zero and unity spin bosons of mass m
in the Duffin–Kemmer–Petiau representation is investigated by means of a unitary …

A relativistic one-particle, quantum theory for spin-zero particles is constructed upon L 2 (x,
ct), resulting in a positive definite spacetime probability density. A generalized Schrödinger …

We construct relativistic wave equations describing the dynamics of two interacting particle
systems involving spin-0 bosons and/or spin-(1/2) fermions. The method consists in …
