Exact Geodesic Distances in FLRW Spacetimes
William J. Cunningham, David Rideout, James Halverson +1
Geodesics are used in a wide array of applications in cosmology and astrophysics. However, it is not a trivial task to efficiently calculate exact geodesic distances in an arbitrar…
Onset of the Asymptotic Regime for Finite Orders
Joe Henson, David P. Rideout, Rafael D. Sorkin +1
We describe a Markov-Chain-Monte-Carlo algorithm which can be used to generate naturally labeled n-element posets at random with a probability distribution of one's choice. Impleme…
A Ground State for the Causal Diamond in 2 Dimensions
Niayesh Afshordi, Michel Buck, Fay Dowker +3
We apply a recent proposal for a distinguished ground state of a quantum field in a globally hyperbolic spacetime to the free massless scalar field in a causal diamond in two-dimen…
Fundamental quantum optics experiments conceivable with satellites -- reaching relativistic distances and velocities
David Rideout, Thomas Jennewein, Giovanni Amelino-Camelia +14
Physical theories are developed to describe phenomena in particular regimes, and generally are valid only within a limited range of scales. For example, general relativity provides…
Network Cosmology
Dmitri Krioukov, Maksim Kitsak, Robert S. Sinkovits +3
Prediction and control of the dynamics of complex networks is a central problem in network science. Structural and dynamical similarities of different real networks suggest that so…
Component Specification in the Cactus Framework: The Cactus Configuration Language
Gabrielle Allen, Tom Goodale, Frank Löffler +3
Component frameworks are complex systems that rely on many layers of abstraction to function properly. One essential requirement is a consistent means of describing each individual…
