Interior Volume

Christodoulou and Rovelli have shown that the interior volume of a Schwarzschild black hole grows linearly with time. The entropy of a scalar field in this interior volume of a Schwarzschild black hole has been calculated and shown to increase linearly with the advanced time too. In this paper, considering Hawking radiation from a d-dimensional charged black hole, we investigate the proportional relation between the entropy of the scalar field in the interior volume and the Bekenstein–Hawking entropy using the method of our previous work. We also derive this proportionality relation using Hamiltonian analysis and find a consistent result. We then investigate the proportionality coefficient with respect to d and find that it gradually decreases as the dimension of space–time increases.

Cauchy Horizon

We study numerically the evolution of space-time inside a black hole under perturbations of non-compact support. Using a very simplified toy model of a spherical charged black hole which is perturbed nonlinearly by a self-gravitating, spherical scalar field, we find that a portion of the Cauchy horizon survives as a non-central, null singularity.

Weak Singularity

We study the Cauchy horizon singularity inside a spherical charged black hole, coupled to a self-gravitating scalar field. We show that all the radial causal geodesics terminate at a weak singularity according to the Tipler classification. Our result is valid anywhere along the singularity, in particular in the regime where nonlinear effects are crucial.

Charged Black Hole

We obtain the solution corresponding to a static charged black hole (Reissner–Nordström black hole) surrounded by quintessence and a cloud of strings, study its thermodynamics and calculate the quasinormal frequencies for a scalar field in this background spacetime. The mass, Hawking temperature and heat capacity are analyzed and the roles played by the sources corresponding to the quintessence and the cloud of strings are showed up. In what concerns the quasinormal modes, we fixed the value of the quintessence parameter [Formula: see text], taking [Formula: see text], calculate the quasinormal frequencies and emphasize the effects due to the cloud of strings.
