Stable Gravastars of Anisotropic Dark Energy
R. Chan, M. F. A. da Silva, P. Rocha +1
Dynamical models of prototype gravastars made of phantom energy are constructed, in which an infinitely thin spherical shell of a perfect fluid with the equation of state $p = (1-γ…
Stable and "bounded excursion" gravastars, and black holes in Einstein's theory of gravity
P. Rocha, R. Chan, M. F. A. da Silva +1
Dynamical models of prototype gravastars are constructed and studied. The models are the Visser-Wiltshire three-layer gravastars, in which an infinitely thin spherical shell of a p…
Towards Exact Quantum Loop Results in the Theory of General Relativity: Status and Update
B. F. L. Ward
We present the status and update of a new approach to quantum general relativity as formulated by Feynman from the Einstein-Hilbert action wherein amplitude-based resummation techn…
Shearing Expansion-free Spherical Anisotropic Fluid Evolution
L. Herrera, N. O. Santos, A. Wang
Spherically symmetric expansionfree distributions are systematically studied. The whole set of field equations and junction conditions are presented for a general distribution of d…
Planck Scale Cosmology in Resummed Quantum Gravity
B. F. L. Ward
We show that, by using resummation techniques based on the extension of the methods of Yennie, Frautschi and Suura to Feynman's formulation of Einstein's theory, we get quantum fie…
Radius Destabilization in Five Dimensional Orbifolds Due to an Enhanced Casimir Effect
Richard K. Obousy, Gerald Cleaver
One of the challenges in connecting higher dimensional theories to cosmology is stabilization of the moduli fields. We investigate the role of a Lorentz violating vector field in t…
