Quantum Mechanical Motion of Relativistic Particle in Non-Continuous Spacetime

arXiv:quant-ph/0212053 · doi:10.1016/S0375-9601(02)01238-0

Abstract

The quantum mechanical motion of a relativistic particle in a non-continuous spacetime is investigated. The spacetime model is a dense, rationale subset of two-dimensional Minkowski spacetime. Solutions of the Dirac equation are calculated using a generalized version of Feynman's checkerboard model. They turn out to be closely related to the continuum propagator.
