WebIn particle physics, the Dirac equation is a relativistic wave equation derived by British physicist Paul Dirac in 1928. In its free form, or including electromagnetic interactions, it describes all spin-1 ⁄ 2 massive particles, called "Dirac particles", such as electrons and quarks for which parity is a symmetry.It is consistent with both the principles of quantum … WebDec 2, 2014 · The Dirac equation is recovered for small wave vector and inertial mass, whereas Lorentz covariance is distorted in the ultrarelativistic limit. The automaton can thus be regarded as a theory unifying scales from Planck to Fermi.
