Dirac Hamiltonian with Imaginary Mass and Induced Helicity—Dependence by Indefinite Metric
Dirac Hamiltonian with Imaginary Mass and Induced Helicity—Dependence by Indefinite Metric
It is of general theoretical interest to investigate the properties of superluminal matter wave equations for spin one-half particles. One can either enforce superluminal propagation by an explicit substitution of the real mass term for an imaginary mass, or one can use a matrix representation of the imaginary unit that …
