The Dirac theory is completely reformulated in terms of Spacetime Algebra, a real Clifford Algebra characterizing the geometrical properties of spacetime. This eliminates redundancy in the conventional matrix formulation and reveals a hidden geometric structure in the theory. Among other things, it reveals that complex numbers in the Dirac equation have a kinematical interpretation, with the unit imaginary identified as the generator of rotations in a spacelike plane representing the direction…

Comment on `Dirac theory in spacetime algebra'
In contrast to formulations of the Dirac theory by Hestenes and by the present author, the formulation recently presented by Joyce (Joyce W P 2001 J. Phys. A: Math. Gen. 34 1991-2005) is equivalent

In contrast to formulations of the Dirac theory by Hestenes and by the current author, the formulation recently presented by W. P. Joyce [J. Phys. A: Math. Gen. 34 (2001) 1991–2005] is equivalent to
Dirac ' s theory in real geometric formalism : multivectors versus spinorsJosep
A fully classical real vector reformulation of Dirac's equation is developed from scratch. It is then shown to be almost equivalent to the Hestenes-Dirac equation when formulated in terms of
Multivector Dirac Equation and ℤ 2-Gradings of Clifford Algebras
AbstractWe generalize certain aspects of Hestenes's approach to Dirac theory to obtain multivector Dirac equations associated to a large class of representations of the gamma matrices. This is done
The Theory of Everything: Foundations, Applications and Corrections to General Relativity
Corrections to general relativity are derived from classical theory and applied to the standard model. The perspective offered is the conceptual inverse of Einstein's theory, where particles exist as
Zitterbewegung in Quantum Mechanics
The possibility that zitterbewegung opens a window to particle substructure in quantum mechanics is explored by constructing a particle model with structural features inherent in the Dirac equation.
Geometric algebra and its application to mathematical physics
Clifford algebras have been studied for many years and their algebraic properties are well known. In particular, all Clifford algebras have been classified as matrix algebras over one of the three
Z2-gradings of Clifford algebras and multivector structures
Let C�(V , g) be the real Clifford algebra associated with the real vector space V ,e ndowed with a nondegenerate metric g .I n this paper, we study the class of Z2-gradings of C�(V , g) which are
One-loop corrections to the seesaw mechanism and models of neutrino masses and lepton mixing
Die Beobachtungen von Neutrinooszillationen belegen, dass Neutrinos sehr kleine, aber von Null verschiene Massen haben. Im Standardmodell der Teilchenphysik werden Neutrinos jedoch als masselos


The Dirac equation is expressed entirely in terms of geometrical quantities by providing a geometrical interpretation for the (−1)½ which appears explicitly in the Dirac equation. In the modification
Observables, operators, and complex numbers in the Dirac theory
The geometrical formulation of the Dirac theory with spacetime algebra is shown to be equivalent to the usual matrix formalism. Imaginary numbers in the Dirac theory are shown to be related to the
States and operators in the spacetime algebra
The spacetime algebra (STA) is the natural, representation-free language for Dirac's theory of the electron. Conventional Pauli, Dirac, Weyl, and Majorana spinors are replaced by spacetime
Clifford Algebra and the Interpretation of Quantum Mechanics
The Dirac theory has a hidden geometric structure. This talk traces the conceptual steps taken to uncover that structure and points out significant implications for the interpretation of quantum
Classical limit of real Dirac theory: Quantization of relativistic central field orbits
AbstractThe classical limit of real Dirac theory is derived as the lowest-order contribution in $$\mathchar'26\mkern-10mu\lambda = \hslash /mc$$ of a new, exact polar decomposition. The resulting
Physics and Probability: The Kinematic Origin of Complex Wave Functions
A reformulation of the Dirac theory reveals that ih has a geometric meaning relating it to electron spin. This provides the basis for a coherent physical interpretation of the Dirac and Schodinger
Imaginary numbers are not real—The geometric algebra of spacetime
This paper contains a tutorial introduction to the ideas of geometric algebra, concentrating on its physical applications. We show how the definition of a “geometric product” of vectors in 2-and
On Decoupling Probability from Kinematics in Quantum Mechanics
A means for separating subjective and objective aspects of the electron wave function is suggested, based on a reformulation of the Dirac Theory in terms of Spacetime Algebra. The reformulation
Local observables in the Dirac theory
By a new method, the Dirac electron theory is completely reexpressed as a set of conservation laws and constitutive relations for local observables, describing the local distribution and flow of
Consistency in the formulation of the Dirac, Pauli, and Schrödinger theories
Properties of observables in the Pauli and Schrodinger theories and first order relativistic approximations to them are derived from the Dirac theory. They are found to be inconsistent with customary
