“…Exact solutions for charged dilaton black holes in which the dilaton is coupled to the Maxwell field have been constructed by many authors. It is found that the presence of dilaton has important consequences on the causal structure and the thermodynamic properties of the black hole [1][2][3][4][5][6][7][8][9]. Thus much interest has been focused on the study of the dilaton black holes.…”

Dilaton black holes in the de Sitter or anti–de Sitter universe

2004

Poletti and Wiltshire have shown that, with the exception of a pure cosmological constant, the solution of a dilaton black hole in the background of de Sitter or anti-de Sitter universe, does not exist in the presence of one Liouville-type dilaton potential. Here with the combination of three Liouvilletype dilaton potentials, we obtain the dilaton black hole solutions in the background of de Sitter or anti-de Sitter universe. PACS number(s): 04

“…The low energy effective action of string theory contains two massless scalars namely dilaton and axion. The dilaton field couples in a nontrivial way to other fields such as gauge fields and results into interesting solutions for the background spacetime [25][26][27][28][29][30]. These solutions [25][26][27][28][29][30], however, are all asymptotically flat.…”

These solutions [25][26][27][28][29][30], however, are all asymptotically flat. In the presence of one or two Liouville-type dilaton potentials, black hole spacetimes which are neither asymptotically flat nor (anti)-de Sitter [(A)dS] have been explored by many authors (see e.g [31][32][33][34][35][36][37][38][39][40]).…”

In this paper, we present the metric for the n-dimensional charged slowly rotating dilaton black hole with N = [(n − 1)/2] independent rotation parameters, associated with N orthogonal planes of rotation in the background of asymptotically flat and asymptotically (anti)-de Sitter spacetime. The mass, angular momentum and the gyromagnetic ratio of such a black hole are determined for the arbitrary values of the dilaton coupling constant. We find that the gyromagnetic ratio crucially depends on the dilaton coupling constant, α, and decreases with increasing α in any dimension.

“…For instance, asymptotically flat black hole solutions in the absence of the dilaton potential were studied in Refs. [18][19][20][21][22][23][24][25][26][27]. In recent years, AdS/CFT correspondence have made asymptotically nonflat solutions more valuable.…”

Thermodynamics of charged rotating dilaton black branes with power-law Maxwell field

In this paper, we construct a new class of charged rotating dilaton black brane solutions, with a complete set of rotation parameters, which is coupled to a nonlinear Maxwell field. The Lagrangian of the matter field has the form of the power-law Maxwell field. We study the causal structure of the spacetime and its physical properties in ample details. We also compute thermodynamic and conserved quantities of the spacetime, such as the temperature, entropy, mass, charge, and angular momentum. We find a Smarr-formula for the mass and verify the validity of the first law of thermodynamics on the black brane horizon. Finally, we investigate the thermal stability of solutions in both the canonical and the grand-canonical ensembles and disclose the effects of dilaton field and nonlinearity of the Maxwell field on the thermal stability of the solutions. We find that, for α ≤ 1, charged rotating black brane solutions are thermally stable independent of the values of the other parameters. For α > 1, the solutions can encounter an unstable phase depending on the metric parameters.
