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 equation. In his first attempts towards a relativistic theory, Dirac consider a Klein-Gordon type equation written in terms of a relativistic Hamiltonian:12, . Upon reading Dirac’s articles using this equation, Ehrenfest asked Dirac in a letter on the motive for using a particular form for the Hamiltonian: In quantum field theory, the nonlinear Dirac equation is a model of self-interacting Dirac fermions. This model is widely considered in quantum physics as a toy model of self-interacting electrons.

Since 2003, the Dirac equation has regained considerable research interests due to the groundbreaking discovery of graphene, the ﬁrst two dimensional material. The dynamics of electrons in graphene can be very well described by the Dirac equation. Therefore the computation for the Dirac equation is of signiﬁcant research value. 2020-12-12 · \begin{equation*} \gamma _ { i } \gamma _ { j } + \gamma _ { j } \gamma _ { i } = 0 , i eq j , i , j = 1,2,3,4.

5. Quantizing the Dirac Field We would now like to quantize the Dirac Lagrangian, L = ¯(x) i @/ m (x)(5.1) We will proceed naively and treat as we did the scalar ﬁeld. But we’ll see that things go wrong and we will have to reconsider how to quantize this theory. 5.1 A Glimpse at the Spin-Statistics Theorem

Dirac expected his relativistic equation to contain the Klein-Gordon equation as its square since this equation involves the relativistic Hamiltonian in its normal invariant form.

So there's the richness of the Dirac Equation extends well beyond its application to relativistic particles.

We consider the following form of the Dirac equation1 (i @ i 5m) = 0 (2) 1 Equation (2) is equivalent to the standard Dirac equation. We can obtain the standard form of the Dirac equation by a simple redeﬁnition of the ﬁeld = M 0, where M= (1 i 5)= p 2 and then multiplying the equation with Mfrom the left.
