The function ei(p.r – Et) is the central player in non-relativistic QM. Yet the expression (p.r – Et) is the Minkowski inner product of the space-time four-vector, (t,r), and the four-momentum (E,p) and as such is Lorentz invariant. According to Feynman, De Broglie realized the relativistic significance of the above expression.
Is there any physical significance to the above in SR? Should the units be regarded as action or angular momentum?
Thanks in advance.
