Encounter between an extended hyperelastic body and a Schwarzschild black hole with quadrupole-order effects
Nishita Jadoo, J. David Brown, Charles R. Evans
We model the general relativistic interaction of a small hyperelastic sphere with a Schwarzschild black hole as it follows an initially marginally-bound orbit through a close encou…
Multigrid elliptic equation solver with adaptive mesh refinement
J. David Brown, Lisa L. Lowe
In this paper we describe in detail the computational algorithm used by our parallel multigrid elliptic equation solver with adaptive mesh refinement. Our code uses truncation erro…
Boundary States and Black Hole Entropy
David Brown
Black hole entropy is derived from a sum over boundary states. The boundary states are labeled by energy and momentum surface densities, and parametrized by the boundary metric. Th…
Duality Invariance of Black Hole Creation Rates
David Brown
Pair creation of electrically charged black holes and its dual process, pair creation of magnetically charged black holes, are considered. It is shown that the creation rates are e…
Black Hole Pair Creation and the Entropy Factor
J. David Brown
It is shown that in the instanton approximation the rate of creation of black holes is always enhanced by a factor of the exponential of the black hole entropy relative to the rate…
Action functionals for relativistic perfect fluids
David Brown
Action functionals describing relativistic perfect fluids are presented. Two of these actions apply to fluids whose equations of state are specified by giving the fluid energy dens…
