Dirac Equation in Quantum Field Theory by jay_dee081651 is a document available to read on EtoBox.
The Dirac equation is a relativistic quantum mechanical wave equation formulated by Paul Dirac in 1928. It provides a description of elementary spin-1⁄2 particles like electrons consistent with both quantum mechanics and special relativity. The equation demands the existence of antiparticles and predated their experimental discovery of the positron. Dirac took the square root of the wave operator and assumed the coefficients were 4x4 matrices, arriving at the Dirac equation which was first-order in both spa
