Physics of the interior of a black hole with an exotic scalar matter

Abstract

We use a numerical code to consider the nonlinear processes arising when a Reissner-Nordstrom black hole is irradiated by an exotic scalar field (modelled as a free massless scalar field with an opposite sign for its energy-momentum tensor). These processes are quite different from the processes arising in the case of the same black hole being irradiated by a pulse of a normal scalar field. In our case, we did not observe the creation of a spacelike strong singularity in the T-region of the space-time. We investigate the antifocusing effects in the gravity field of the exotic scalar field with the negative energy density and the evolution of the mass function. We demonstrate the process of vanishing of the black hole when it is irradiated by a strong pulse of an exotic scalar field.Comment: 16 pages, 16 figures.

Precision tests of parity violation over cosmological distances

“…In Ohm's words, this was attributed to the fact that "the '+' temperature possibilities of [the receiver temperature uncertainties] must predominate" [16]. Doroshkevich and Novikov cited Ohm's paper in a 1964 review of cosmic radiation predicted in Gamow's theory of the origin of the universe [17]. Perhaps due to a misinterpretation of the 3.3 K excess, Doroshkevich and Novikov attributed the excess temperature to emission from the Earth's atmosphere.…”

Charged black holes in string-inspired gravity. I. Causal structures and responses of the Brans-Dicke field

“…To the best knowledge of the authors, the double-null formalism is one of the most efficient techniques to investigate the interior of the black holes [32] and we have priviously used this approach with good success [47-49, 57, 66]. There are some previous works regarding string-inspired models using the double-null formalism [33][34][35][36][37][38][39][40][41][42][43][44] and other methods [45,46] as well as the authors' previous works [47][48][49][50][51][52][53][54][55]. In this paper we will investigate a wide parameter space, for example, we will cover not only directly stringinspired models, but also indirectly string-inspired models (f (R) inspired model [56]) as well as natural generalizations of the parameters, e.g., the ghost limit.…”

“…where Equations (3.31) and (3.39) are evolution equations for α ,uv , r ,uv , Φ ,uv and s ,uv , which can be solved with the same integration scheme used in the authors' previous papers [47][48][49]57]. The gauge field a can be evolved using the same numerical scheme via Equation (3.38) or we can evolve a and q via Equations (3.34) and (3.35).…”

“…For this reason we refer to that paper and references therein (especially, [47][48][49]), for further details of the numerical schemes and other details related to the design of the code.…”

Stability analysis of a Morris-Thorne-Bronnikov-Ellis wormhole with pressure

“…Therefore, much attention is given to this question in the literature (see [1][2][3][4][5][6][7][8][9]). The simplest wormhole model [10][11][12] (a phantom scalar field with a negative kinetic term) turned out to be unstable, contrary to the erroneous assertions in [1,2] and in accordance with the more recent (indepen dent) correct studies [3][4][5][6][7]13]). The more complex model of the same wormhole with the same metric [6,7] (a radial magnetic field and phantom dust with a negative mass density) turned out to be almost stable against all spherical perturbation modes (except the longitudinal radial dust motion by inertia).…”
