The mathematical Formalism Klein-Gordon equation Dirac equation Solutions with negative Energies For an electron in rest the Dirac equation becomes i ∂ ∂t φ χ = m 1 0 0 −1 φ χ . The solutions are φ= e−iω0t and χ= e+iω0t. The energies become E φ = +~ω 0 2019-12-01 · We construct general solutions of the time-dependent Dirac equation in (1+1) dimensions with a Lorentz scalar potential, subject to the so-called Majorana condition, in the Majorana representation. In this situation, these solutions are real-valued and describe a one-dimensional Majorana single particle.

In its free form it describes all spin-1 In Ashok Das Lecture on QFT book, pg. 40, the solution of the Dirac equation for the general motion of a free particle with mass $m$ along an arbitrary direction is given by $$psi (x)=int d^4p a(p) delta(p^2-m^2)e^{-ipx}u(p),$$ The theorem of existence of solution of the Dirac equationrequires an important modification to the Dirac angular momentum constantthat was defined by Dirac's algebra.

The Dirac equation and its solutions - CERN Document Server

The general solution is actually a superposition of waves with all possible momenta (and spins*). The Dirac equation is one of the two factors, and is conventionally taken to be p m= 0 (31) Making the standard substitution, p !i@ we then have the usual covariant form of the Dirac equation (i @ m) = 0 (32) where @ = (@ @t;@ @x;@ @y;@ @z), m is the particle mass and the matrices are a set of 4-dimensional matrices. In 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-½ massive particles such as electrons and quarks for which parity is a symmetry. In this paper Dirac equation for two electromagnetic potentials viz vector potential and scalar potential have been solved. These solutions of the Dirac equa- tion are written in terms of known solutions of the SchrOdinger equation.
