Rotating black holes with Nil or SL(2,$\,\mathbb{R}$) horizons / F.M. Faedo, S. Klemm, P. Mariotti. - In: JOURNAL OF HIGH ENERGY PHYSICS. - ISSN 1029-8479. - (2023), pp. 1-25. [Epub ahead of print] [10.1007/JHEP05(2023)138]
Abstract:
We construct rotating black holes in $N=2$, $D=5$ minimal and matter-coupled
gauged supergravity, with horizons that are homogeneous but not isotropic. Such
spaces belong to the eight Thurston model geometries, out of which we consider
the cases Nil and SL$(2,\mathbb{R})$. In the former, we use the recipe of
arXiv:hep-th/0304064 to directly rederive the solution that was obtained by
Gutowski and Reall in arXiv:hep-th/0401042 as a scaling limit from a spherical
black hole. With the same techniques, the first example of a black hole with
SL$(2,\mathbb{R})$ horizon is constructed, which is rotating and one quarter
BPS. The physical properties of this solution are discussed, and it is shown
that in the near-horizon limit it boils down to the geometry of
arXiv:hep-th/0401042, with a supersymmetry enhancement to one half. Dimensional
reduction to $D=4$ gives a new solution with hyperbolic horizon to the t$^3$
model that carries both electric and magnetic charges. Moreover, we show how to
get a nonextremal rotating Nil black hole by applying a certain scaling limit
to Kerr-AdS$_5$ with two equal rotation parameters, which consists in zooming
onto the north pole of the S$^2$ over which the S$^3$ is fibered, while
boosting the horizon velocity effectively to the speed of light.
