“…Now, when α → 0, the scalar potential V (φ) and rotating black hole solution f (r) reduce to the static counterparts of the static black hole solution in three-dimensional Einstein gravity with a nonminimally coupled scalar field [20].…”

“…In three dimensional Einstein gravity, some static black holes with minimally [31] or nonminimally [20,32] coupled scalar hairs were found. Moreover, the thermodynamical properties of these hairy black holes were studied in [15,33,34], where the first law of black hole thermodynamics was found always hold.…”

Introducing a new form of scalar potential V (φ), we derive a proper form of the rotating black hole solution in three-dimensional Einstein gravity with nonminimally coupled scalar field and find that the first law of thermodynamics of this new rotating hairy black hole can be protected, where the scalar field parameter B is constrained to relate to the black hole size. We also disclose the Hawking-Page phase transition between this rotating hairy black holes and the pure thermal radiation. Moreover, we study phase transitions between this rotating hairy black hole and rotating BTZ black hole. Considering the matchings for the temperature and angular momentum, we find that the rotating BTZ black hole always has smaller free energy which is a thermodynamically more preferred phase. Additionally, we evaluate the thermodynamics of the rotating black hole with minimally coupled scalar hair in three dimensions, which exhibits that the thermodynamical behaviors of this rotating hairy black hole are very similar to those of the rotating black hole with nonminimally coupled scalar hair.

“…Next we consider the hairy black hole solution in the Jordan frame, for Λ = 3 ℓ 2 > 0. This is a black hole solution in the Einstein theory with a self-interacting and conformally coupled scalar field (see [26,27]). One has C(r) = − r 2 ℓ 2 + (r + r 0 ) 2 r 2 , and ψ(r) = 0 , (4.9)…”

Following recent literature on dS instability in presence of interactions, we study the decay of massive particles in general FRW models and the emission from naked singularities either associated with 4D charged black holes or 2D shock waves, by means of the Hamilton-Jacobi tunneling method. It is shown that the two-dimensional semi-classical tunneling amplitude from a naked singularity computed in that way is the same as the one-loop result of quantum field theory.

“…Nevertheless, when a negative cosmological constant is considered, the no-hair theorems can usually be circumvented, and then there exists a broad literature of black hole solutions with a (non)minimal scalar field in the four or higher dimensional Einstein's gravity, including static [5][6][7][8][9][10][11][12][13][14], and rotating [15][16][17] extensions with a complex, massive scalar field and in higher order derivative gravity [18][19][20][21].…”

We obtain an exact static solution to Einstein-Power-Maxwell (EPM) theory in (2 + 1) dimensional AdS spacetime, in which the scalar field couples to gravity in a non-minimal way. After considering the scalar potential, a stable system leads to a constraint on the power parameter k of Maxwell field. The solution contains a curvature singularity at the origin and is non-conformally flat. The horizon structures are identified, which indicates the physically acceptable lower bound of mass in according to the existence of black hole solutions. Especially for the cases with k > 1, the lower bound is negative, thus there exist scalar black holes with negative mass. The null geodesics in this spacetime are also discussed in detail. They are divided into five models, which are made up of the cases with the following geodesic motions: no-allowed motion, the circular motion, the elliptic motion and the unbounded spiral motion.
