Causal Set Phenomenology
Lydia Philpott
Central to the development of any new theory is the investigation of the observable consequences of the theory. In the search for quantum gravity, research in phenomenology has bee…
Polarization Diffusion from Spacetime Uncertainty
Carlo Contaldi, Fay Dowker, Lydia Philpott
A model of Lorentz invariant random fluctuations in photon polarization is presented. The effects are frequency dependent and affect the polarization of photons as they propagate t…
Particle simulations in causal set theory
Lydia Philpott
Models of particle propagation in causal set theory are investigated through simulations. For the swerves model the simulations are shown to agree with the expected continuum diffu…
Energy-momentum diffusion from spacetime discreteness
Fay Dowker, Lydia Philpott, Rafael Sorkin
We study potentially observable consequences of spatiotemporal discreteness for the motion of massive and massless particles. First we describe some simple intrinsic models for the…
