The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

We present and analyze exact solutions of the Einstein-Maxwell and Einstein-Maxwell-Dilaton equations that describe static pairs of oppositely charged extremal black holes, i.e., black diholes. The holes are suspended in equilibrium in an external magnetic field, or held apart by cosmic strings. We comment as well on the relation of these solutions to brane-antibrane configurations in string and M-theory.

  • It would, indeed be quite interesting to study in detail the horizon (and ergosphere) geometry of these solutions.[The fact that the extremality limit has $|J|>M^2$ has a counterpart for the charged dihole [ref] wherein the extremal limit has $|Q|>M$.

  • Our construction is also distinct from the “black dihole” [ref] implementations of Kerr, which are simply just real metrics and involve no self-duality relation between mass and NUT charge.
