Evolution of spherical overdensity in Chaplygin gas model
Amin Rezaei Akbarieh, Mohammad Ahmadi, Yousef Izadi +2
Even though many scalar field models of dark energy have been considered in the literature, there is another interesting class of dark energy models involving a fluid known as a Ch…
Higher dimensional quantum communication in a curved spacetime: an efficient simulation of the propagation of the wavefront of a photon
Warner A. Miller, Paul M. Alsing, Doyeol Ahn
A photon with a modulated wavefront can produce a quantum communication channel in a larger Hilbert space. For example, higher dimensional quantum key distribution (HD-QKD) can enc…
Wang and Yau's Quasi-Local Energy for an Extreme Kerr Spacetime
Warner A. Miller, Shannon Ray, Mu-Tao Wang +1
There exist constant radial surfaces, , that may not be globally embeddable in for Kerr spacetimes with . To compute the Brown and York (…
Adiabatic Isometric Mapping Algorithm for Embedding 2-Surfaces in Euclidean 3-Space
Shannon Ray, Warner A. Miller, Paul M. Alsing +1
Alexandrov proved that any simplicial complex homeomorphic to a sphere with strictly non-negative Gaussian curvature at each vertex can be isometrically embedded uniquely in $\math…
Distributed mean curvature on a discrete manifold for Regge calculus
Rory Conboye, Warner A. Miller, Shannon Ray
The integrated mean curvature of a simplicial manifold is well understood in both Regge Calculus and Discrete Differential Geometry. However, a well motivated pointwise definition…
New efficient algorithm for the isometric embedding of 2-surface metrics in 3 dimensional Euclidean space
Wolfgang Tichy, Jonathan R. McDonald, Warner A. Miller
We present a new numerical method for the isometric embedding of 2-geometries specified by their 2-metrics in three dimensional Euclidean space. Our approach is to directly solve t…
