Binding in charged spherically symmetric objects
Matthew Corne, Arkady Kheyfets, Jennifer Piasio +1
We consider the subject of self--binding in static, spherically symmetric objects consisting of a charged fluid. We have shown previously that in the case of a perfect fluid, only…
A Kirchhoff-like conservation law in Regge calculus
Adrian P. Gentle, Arkady Kheyfets, Jonathan R. McDonald +1
Simplicial lattices provide an elegant framework for discrete spacetimes. The inherent orthogonality between a simplicial lattice and its circumcentric dual yields an austere repre…
Non--Localizability of Electric Coupling and Gravitational Binding of Charged Objects
Matthew Corne, Arkady Kheyfets, Warner Miller
The energy--momentum tensor in general relativity contains only localized contributions to the total energy--momentum. Here, we consider a static, spherically symmetric object cons…
Quantum Geometrodynamics of the Bianchi IX cosmological model
Arkady Kheyfets, Warner A. Miller, Ruslan Vaulin
The canonical quantum theory of gravity -- Quantum Geometrodynamics (QG) is applied to the homogeneous Bianchi type IX cosmological model. As a result, the framework for the quantu…
The constraints as evolution equations for numerical relativity
Adrian P. Gentle, Nathan D. George, Arkady Kheyfets +1
The Einstein equations have proven surprisingly difficult to solve numerically. A standard diagnostic of the problems which plague the field is the failure of computational schemes…
The Issue of Time in Quantum Geometrodynamics
Nathan D. George, Adrian P. Gentle, Arkady Kheyfets +1
Standard techniques of canonical gravity quantization on the superspace of 3--metrics are known to cause insurmountable difficulties in the description of time evolution. We forwar…
