Evolving of a massless scalar field in Reissner-Nordström Anti-de Sitter spacetimes
نویسندگان
چکیده
We investigate the evolution of a scalar field propagating in Reissner-Nordström Anti-de Sitter spacetime. Due to the characteristic of spacetime geometry, the radiative tails associated with a massless scalar field propagation have an oscillatory exponential decay. The object-picture of the quasinormal ringing has also been obtained. For small charges, the approach to thermal equilibrium is faster for larger charges. However, after the black hole charge reaches a critical value, we get the opposite behavior for the imaginary frequencies of the quasinormal modes. Some possible explanations concerning the wiggle of the imaginary frequencies have been given. The picture of the quasinormal modes depending on the multipole index has also been illustrated.

Reissner–Nordström Anti-de Sitter Black Holes in Mimetic F(R) Gravity
In this paper, we study under which conditions the Reissner–Nordström anti-de Sitter black hole can be a solution of the vacuum mimetic F(R) gravity with Lagrange multiplier and mimetic scalar potential. As the author demonstrates, the resulting picture in the mimetic F(R) gravity case is a trivial extension of the standard F(R) approach, and in effect, the metric perturbations in the mimetic F...
متن کاملOn the Classification of Asymptotic Quasinormal Frequencies for d–Dimensional Black Holes and Quantum Gravity
We provide a complete classification of asymptotic quasinormal frequencies for static, spherically symmetric black hole spacetimes in d dimensions. This includes all possible types of gravitational perturbations (tensor, vector and scalar type) as described by the Ishibashi–Kodama master equations. The frequencies for Schwarzschild are dimension independent, while for Reissner–Nordstrøm are dim...
متن کاملQuasinormal Modes and Choptuik Scaling in the Near Extremal Reissner-Nordström Black Hole
We study quasinormal modes of massless scalar and fermion fields in the near extremal Reissner-Nordström black hole, and relate them to Choptuik scaling form following a recently proposed analytic approach. For both massless cases, quasinormal modes are shown to be proportional to the black hole horizon and the Hawking temperature, and the critical exponents are the same, although for the fermi...
متن کاملTall tales from de Sitter space II: Field theory dualities
We consider the evolution of massive scalar fields in (asymptotically) de Sitter spacetimes of arbitrary dimension. Through the proposed dS/CFT correspondence, our analysis points to the existence of new nonlocal dualities for the Euclidean conformal field theory. A massless conformally coupled scalar field provides an example where the analysis is easily explicitly extended to ‘tall’ backgroun...
