Considerations of particle definitions in the functional Schroedinger formalism
Alex Venditti, Charles Dyer
It is often remarked in the literature that particles in QFT on curved spacetime are akin to coordinates in general relativity and hence are physically meaningless. This moral is g…
Velocity dominated singularities in the cheese slice universe
Dan Giang, Charles C. Dyer
We investigate the properties of spacetimes resulting from matching together exact solutions using the Darmois matching conditions. In particular we focus on the asymptotically vel…
Aspects of Causality in the Parallelisable Implicit Evolution Scheme
Parandis Khavari, Charles C. Dyer
A (3+1)-evolutionary method in the framework of Regge Calculus, essentially a method of approximating manifolds with rigid simplices, makes an excellent tool to probe the evolution…
Multifractal Analysis of Packed Swiss Cheese Cosmologies
J. R. Mureika, C. C. Dyer
The multifractal spectrum of various three-dimensional representations of Packed Swiss Cheese cosmologies in open, closed, and flat spaces are measured, and it is determined that t…
