Pure Real Solutions to the Dirac-Coulomb Problem in Majorana Representation
By exploiting the Majorana representation of the gamma matrices, we first rewrite the free Dirac equation without complex numbers, then we show that the minimal complex electromagnetic coupling could be handled also without complex numbers by just considering two coupled real fields instead of one complex field. When done, we …
