Covariant formulations of BSSN and the standard gauge
J. David Brown
The BSSN and standard gauge equations are written in covariant form with respect to spatial coordinate transformations. The BSSN variables are defined as tensors with no density we…
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…
Excision without excision: the relativistic turducken
David Brown, Olivier Sarbach, Erik Schnetter +4
to turducken (turduckens, turduckening, turduckened, turduckened) [math.]: To stuff a black hole. We analyze and apply an alternative to black hole excision based on smoothing the…
BSSN in Spherical Symmetry
David Brown
The BSSN (Baumgarte-Shapiro-Shibata-Nakamura) formulation of the Einstein evolution equations is written in spherical symmetry. These equations can be used to address a number of t…
Puncture Evolution of Schwarzschild Black Holes
J. David Brown
The moving puncture method is analyzed for a single, non-spinning black hole. It is shown that the puncture region is not resolved by current numerical codes. As a result, the geom…
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…
