## A Causal Net Approach to Relativistic Quantum Mechanics

**Authors:** R.D. Bateson

In this paper we discuss a causal network approach to describing relativistic quantum
mechanics where each vertex on a causal net represents a possible point event or particle
observation. By constructing the simplest causal net based on Reichenbach-like conjunctive
forks in proper time we can exactly derive the 1+1 dimension Dirac equation for a
relativistic fermion and correctly model quantum mechanical statistics. Symmetries of the
net provide various quantum mechanical effects such as quantum uncertainty and wavefunction,
phase, spin, negative energy states and the effect of a potential. The causal net can be
embedded in 3+1 dimensional space-time and is consistent with the conventional Dirac equation.
In the low velocity limit the causal net approximates to the Schrödinger equation and Pauli
equation for a fermion in an electromagnetic field. Extending to different momentum states
the net is compatible with the Feynman path integral approach to quantum mechanics that
allows calculation of well known quantum phenomena such as diffraction.
