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

2 Sz =± N S e- B A ψ ψ 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 3 Dirac equation 3.1 Dirac equation for the free electron Every solution of the equation: E c X i ^ ip i m^ ec2! = 0 (9) is a solution for (5). With the aid of the correspondic principle the linearization can be written as i~ @ @t + i~c ^ r m^ ec2 j (~r;t)i= 0 (10) and it is called the Dirac equation … 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. Transforming the Dirac Equation: iµ⇤ µ⇥ mc ⇥ =0 ⇥ iµ⇤ µ⇥ mc ⇥ =0 iµ ⇤x⇥ ⇤xµ ⇤ ⇥ (S⇥) mc (S⇥)=0 S is constant in space time, so we can move it to the left of the derivatives iµS ⇤x⇥ ⇤xµ ⇤ ⇥ ⇥ mc (S⇥)=0 Now slap S-1 from both sides Since these equations must be the same, S must satisfy i 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 Dirac’s equation is a relativistic wave equation which explained that for all half-spin electrons and quarks are parity inversion (sign inversion of spatial coordinates) is symmetrical. The equation was first explained in the year 1928 by P. A. M. Dirac. Dirac spinors, although they have four components, are not four-vectors - to determine how a Dirac spinor transforms, need to consider Ψ as seen in two inertial frames, then x There must exist a 4x4 matrix S, such that: • for a Lorentz transformation along the x-axis (show this!) ± Dirac Equation… 2. How Not to Quantize the Dirac Field: a Lesson in Spin and Statistics We start in the usual way and deﬁne the momentum, π= ∂L ∂ψ˙ = iψγ¯ 0 = iψ†. (2) Thus, for the Dirac Lagrangian, the momentum conjugate to ψis iψ†. It does not involve the time derivative of ψ.

They are also quite important to understand.

2016-01-20 · View image of Stylised Dirac Equation (Credit: Stellario Cama) "Aesthetically it is elegant and simple," says Jim Al-Khalili of the University of Surrey in Guildford, UK. 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. 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 We now rewrite the wave equation using these definitions: i ∂t =(αp+βm)Ψ Multiply from the left by β iβ ∂t =(βαp+m)Ψ or 0(iγ ∂ ∂t +iγ∇− m)Ψ =0 or (iγµ∂ µ− m)Ψ =0. In an electromagnetic field we make the canonical substitution ∂ µ → D µ = ∂ µ +ieA µ giving the Dirac equation γµ(i∂ (µ −eA µ)−m)Ψ= 0 Dirac equation is the relativistic extension to Shrodinger's equation. Instead of considering classical energy conservation we consider E^2=m^2*c^4+p^2*c^2 And plug the quantum operators instead of E and p We get: Div^2 - 1/c^2*d^2/dt^2=m^2*c^2/h-bar^2 Which is the Dirac equation.
