Wataru Ichinose?, On the Feynman Path Integral for the Dirac Equation in the General Dimensional Spacetime, Communications in Mathematical Physics 329, 83–508 (2014), doi. The Dirac equation in quaternionic format By J.A.J. van Leunen Last modified: 3 december 2015 ABSTRACT In its original form the Dirac equation for the free electron and the free positron is formulated by using complex number based spinors and matrices. That equation can be split into two equations, one for the electron and one for the positron.

## 4. The Dirac Equation “A great deal more was hidden in the Dirac equation than the author had expected when he wrote it down in 1928. Dirac himself remarked in one of his talks that his equation was more intelligent than its author. It should be added, however, that it was Dirac who found most of the additional insights.” Weisskopf on Dirac

The Dirac equation is invariant under charge conjugation, defined as changing electron states into the opposite charged positron states with the same momentum and spin (and changing the sign of external fields). To do this the Dirac spinor is transformed according to. 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.

First of all, he postulated another equation, linear in \(\partial/\partial t\) to ensure that the probability density will be positive definite, and also linear in \(\nabla\) for purposes of relativistic covariance: This equation is called the real Dirac equation, because no complex scalars are involved. Some physicists recoil at ﬂrst sight of the explicit ° 2° 1 and ° 0 in (8), claiming immediately that the equation cannot be Lorentz covariant. However, covari-ance is easily proved [3], and the mistaken impression that (8) is … 2021-01-21 The free-particle Dirac equation is derived.

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.
