Phenomenological Quantum Gravity
Dagny Kimberly, Joao Magueijo
These notes summarize a set of lectures on phenomenological quantum gravity which one of us delivered and the other attended with great diligence. They cover an assortment of topic…
Bouncing Universes with Varying Constants
John D. Barrow, Dagny Kimberly, Joao Magueijo
We investigate the behaviour of exact closed bouncing Friedmann universes in theories with varying constants. We show that the simplest BSBM varying-alpha theory leads to a bouncin…
Varying Alpha and the Electroweak Model
Dagny Kimberly, Joao Magueijo
Inspired by recent claims for a varying fine structure constant, alpha, we investigate the effect of ``promoting coupling constants to variables'' upon various parameters of the st…
Non-Linear Relativity in Position Space
Dagny Kimberly, João Magueijo, João Medeiros
We propose two methods for obtaining the dual of non-linear relativity as previously formulated in momentum space. In the first we allow for the (dual) position space to acquire a…
Chiral Supergravitons Interacting with a 0-Brane N-Extended NSR Super-Virasoro Group
A. Boveia, S. James Gates, Bjorg A. Larson +4
We continue the development of the actions, S_{AFF}, by examining the cases where there are N fermionic degrees of freedom associated with a 0-brane. These actions correspond to th…
Loitering Phase in Brane Gas Cosmology
Robert Brandenberger, Damien A. Easson, Dagny Kimberly
Brane Gas Cosmology (BGC) is an approach to M-theory cosmology in which the initial state of the Universe is taken to be small, dense and hot, with all fundamental degrees of freed…
