20.500.12556/DKUM-89025 Long-range forces between nonidentical black holes with non-BPS extremal limits Motivated by recent studies of long-range forces between identical black holes, we extend these considerations by investigating the forces between two nonidentical black holes. We focus on classes of theories where charged black holes can have extremal limits that are not BPS. These theories, which live in arbitrary spacetime dimension, comprise gravity coupled to N 2-form field strengths and (N − 1) scalar fields. In the solutions we consider, each field strength carries an electric charge. The black hole solutions are governed by the SLðN þ 1; RÞ Toda equations. In four dimensions, the black hole solutions in the SLð3; RÞ example are equivalent to the “Kaluza-Klein dyons.” We find that any pair of such extremal black holes that are not identical (up to overall scaling) will repel one another. We also show that there can exist pairs of non-extremal, nonidentical black holes which obey a zero-force condition. Finally, we find indications of similar results in the higher examples, such as SLð4; RÞ. astronomy astrophysics black holes spacetime dimensions astronomija astrofizika črne luknje dimenzija prostor-čas true false true American Physical Society Angleški jezik Slovenski jezik Znanstveno delo 2024-06-06 07:57:04 2024-06-06 08:23:42 2024-06-07 03:17:49 0000-00-00 00:00:00 2022 0 0 Str. 1-14 Št. 8, št. članka 086007 Letn. 106 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-08-11 2022-09-18 2022-10-13 521 192634115 10.1103/PhysRevD.106.086007 2470-0029 Cremonini-2022-Long-range_forces_between_nonid.pdf Cremonini-2022-Long-range_forces_between_nonid.pdf 1 3AC3F9432B06F3588C1616BE62D5752B 1b7bae2d2a6b6f80827e4dca21f96399703999dbfd1f4e2ab8dba33e819a8ba7 205293ee-23cd-11ef-9cfe-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=180248 https://doi.org/10.1103/PhysRevD.106.086007 0 a847e95e-23c9-11ef-9cfe-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=180247 Univerza v Mariboru 0 0 0
