On the "renormalization" transformations induced by cycles of expansion and contraction in causal set cosmology
X. Martin, D. O'Connor, D. P. Rideout +1
We study the ``renormalization group action'' induced by cycles of cosmic expansion and contraction, within the context of a family of stochastic dynamical laws for causal sets der…
High quality factor measured in fused silica
Steven D. Penn, Gregory M. Harry, Andri M. Gretarsson +5
We have measured the mechanical dissipation in a sample of fused silica drawn into a rod. The sample was hung from a multiple-bob suspension, which isolated it from rubbing against…
Evidence for a continuum limit in causal set dynamics
D. P. Rideout, R. D. Sorkin
We find evidence for a continuum limit of a particular causal set dynamics which depends on only a single ``coupling constant'' and is easy to simulate on a computer. The model…
Indications of causal set cosmology
Rafael D. Sorkin
Within the context of a recently proposed family of stochastic dynamical laws for causal sets, one can ask whether the universe might have emerged from the quantum-gravity era with…
