Scattering of low-energy electrons and positrons by atomic beryllium: Ramsauer-Townsend effect
David D. Reid, J. M. Wadehra
Total cross sections for the scattering of low-energy electrons and positrons by atomic beryllium in the energy range below the first inelastic thresholds are calculated. A Ramsaue…
A numerical study of the correspondence between paths in a causal set and geodesics in the continuum
Raluca Ilie, Gregory B. Thompson, David D. Reid
This paper presents the results of a computational study related to the path-geodesic correspondence in causal sets. For intervals in flat spacetimes, and in selected curved spacet…
Scattering of low- to intermediate-energy positrons from molecular hydrogen
David D. Reid, William B. Klann, J. M. Wadehra
Using a complex model potential, we have calculated the total, integrated elastic, momentum transfer, absorption, and differential cross sections for positrons scattered from molec…
The picture of our universe: A view from modern cosmology
David D. Reid, Daniel W. Kittell, Eric E. Arsznov +1
In this paper we give a pedagogical review of the recent observational results in cosmology from the study of type Ia supernovae and anisotropies in the cosmic microwave background…
Manifold dimension of a causal set: Tests in conformally flat spacetimes
David D. Reid
This paper describes an approach that uses flat-spacetime dimension estimators to estimate the manifold dimension of causal sets that can be faithfully embedded into curved spaceti…
Introduction to causal sets: an alternate view of spacetime structure
David D. Reid
This paper provides a thorough introduction to the causal set hypothesis aimed at students, and other interested persons, with some knowledge of general relativity and nonrelativis…
