## The Dirac Equation: Numerical and Asymptotic Analysis - GUPEA

The Dirac Equation: Numerical and Asymptotic Analysis Hasan Almanasreh ISBN 978-91-628-8593-9 °c Hasan Almanasreh, 2012 Division of Mathematics Physics Platform (MP 2) the derivation method used, Relativistic Domain theory. The initial part of the derivation of the standard Dirac equation, is a re-formulation of the Klein-Gordon, which is then augmented via the insertion of Dirac's gamma matrices, to account for both clockwise and anti-clockwise spin, and for both positive and negative energy solutions. Depending on the notion of the moment, the physical Dirac equation is variously one mathematical equation, or a collection of mathematical equation elements. In this formulation, the [physical] Dirac spinor field equation (which [comprises] four complex equation [elements], and so eight equation [elements] in total) equation is derived to be the condition the particle eigenfunction must satisfy, at each space-time point, in order to fulfill the averaged energy relation.

In this section we are only interested in the Dirac equation, so we write the Lagrangian as: For the Dirac Lagrangian, the momentum conjugate to is i †.Itdoesnotinvolve the time derivative of .Thisisasitshouldbeforanequationofmotionthatisﬁrst order in time, rather than second order. This is because we need only specify and † on an initial time slice to determine the full evolution.

We only require the Dirac equation to admit two The Dirac equation describes the behaviour of spin-1/2 fermions in relativistic quantum ﬁeld theory. For a free fermion the wavefunction is the product of a plane wave and a Dirac spinor, u(pµ): ψ(xµ)=u(pµ)e−ip·x(5.21) Substituting the fermion wavefunction, ψ, … Multiply the non-conjugated Dirac equation by the conjugated wave function from the left and multiply the conjugated equation by the wave function from right and subtract the equations.
