There is a minor problem in attempting to write the Hermitian conjugate of this equation since the Dirac Equation. Consider the motion of an electron in the absence of an electromagnetic field. In classical relativity, electron energy, , is related to electron momentum, , according to the well-known formula. (1112) where is the electron rest mass. The quantum mechanical equivalent of this expression is the wave equation. Derivation of the adjoint of Dirac equation. My process: I started with Dirac equation ( i γ μ ∂ μ − m) ψ = 0.

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. It is consistent with both the principles of quantum mechanics and the theory of special relativity, and was the first theory to account fully for special relativity in the context of quantum mechanics. It was We are therefore led to the Dirac equation with electromagnetic potentials:c i ∂ ∂ct − e c A 0 ψ = cα · p − e c A +βm 0 c 2 ψ, or i ∂ ∂t ψ = cα · p − e c A + eA 0 +βm 0 c 2 ψ.

The Dirac Equation . Quantum mechanics is based on a correspondence principle that maps classical dynamical variables to differential operators. From the classical equation of motion for a given object, expressed in terms of energy E and momentum p, the corresponding wave equation of quantum mechanics is given by making the replacements Derivation of Dirac Equation Form Using Complex Vector Mohammed Sanduk Chemical and Process Engineering Department, University of Surrey, Guildford, Notice that the Lagrangian happens to be zero for the solution of Dirac equation (e.g. the extremum of the action).

Velocity eigenvalues for electrons are always along any direction. Thus the only values of velocity that we could measure are . Localized states, expanded in plane waves, contain all four components of the plane wave solutions. The Lagrangian density for a Dirac field is. L = i ψ ¯ γ μ ∂ μ ψ − m ψ ¯ ψ.
