Two Zitterbewegung Formalism?

In a previous preprint, we consider the idea that quantum formalism is contained in Einstein´s 1905 energy momentum equation if one allows for +E and -E. In this preprint, we examine two formalisms for calculating Zitterbewegung. The first follows that of Schrodinger (1930) and forces us to assume [p,x]=1. For p=0, however, one can directly obtain an X matrix for our one dimensional 2x2 case. The Schrodinger result equals the second result when p=0. No X matrix, however, exists such that [H, X] = V for p>0.
