A Clifford algebra model in phase space

Abstract

I show how the isomorphism between the Lie groups of types $B_2$ and $C_2$ leads to a faithful action of the Clifford algebra $\mathcal C\ell(3,2)$ on the phase space of 2-dimensional dynamics, and hence to a mapping from Dirac spinors modulo scalars into this same phase space. Extending to the phase space of 3-dimensional dynamics allows one to embed all the gauge groups of the Standard Model as well, and hence unify the electro-weak and strong forces into a single algebraic structure, identified as the gauge group of Hamiltonian dynamics. The gauge group transforms between phase space coordinates appropriate for arbitrary observers, and therefore shows how the apparently arbitrary parameters of the Standard Model transform between mutually accelerating observers. In particular, it is possible to calculate the transformation between an inertial frame and the laboratory frame, in order to explain how macroscopic laboratory mechanics emerges from quantum mechanics, and to show how to write down a quantum theory of gravity that is consistent with quantum mechanics, but is not consistent with General Relativity.
