Generating new magnetic universe solutions from old
David Garfinkle, M. A. Melvin
In this paper we apply the techniques which have been developed over the last few decades for generating nontrivially new solutions of the Einstein-Maxwell equations from seed solu…
Collapse of a Circular Loop of Cosmic String
David Garfinkle, G. Comer Duncan
We study the collapse of a circular loop of cosmic string. The gravitational field of the string is treated using the weak field approximation. The gravitational radiation from the…
Entropy in Black Hole Pair Production
D. Garfinkle, S. B. Giddings, A. Strominger
Pair production of Reissner-Nordstrom black holes in a magnetic field can be described by a euclidean instanton. It is shown that the instanton amplitude contains an explicit facto…
Results on exact solutions of low energy string theory
David Garfinkle
A family of solutions to low energy string theory is found. These solutions represent waves traveling along "extremal black strings"
