A Scalar Field and the Einstein Vacuum in Modern Kaluza-Klein Theory (1209.5703v2)
Published 23 Sep 2012 in gr-qc
Abstract: Five-dimensional relativity as an extension of general relativity has field equations that simplify considerably given the adoption of a new gauge. The result is a scalar field governed by the Klein-Gordon equation, in an empty spacetime with a cosmological constant governed by Einstein's equations. The main application is to the properties of massive particles in a vacuum-dominated universe.
