Charged Black Holes with Yukawa Potential
arxiv(2024)
摘要
This study derives a novel family of charged black hole solutions featuring
short- and long-range modifications. These ones are achieved through a
Yukawa-like gravitational potential modification and a nonsingular electric
potential incorporation. The short-range corrections encode quantum gravity
effects, while the long-range adjustments simulate gravitational effects akin
to those attributed to dark matter. Our investigation reveals that the total
mass of the black hole undergoes corrections owing to the apparent presence of
dark matter mass and the self-adjusted electric charge mass. Two distinct
solutions are discussed: a regular black hole solution characterizing small
black holes, where quantum effects play a crucial role, and a second solution
portraying large black holes at considerable distances, where the significance
of Yukawa corrections comes into play. Notably, these long-range corrections
contribute to an increase in the total mass and hold particular interest as
they can emulate the role of dark matter. Finally, we explore the
phenomenological aspects of the black hole. Specifically, we examine the
influence of electric charge and Yukawa parameters on thermodynamic quantities,
the quasinormal modes for the charged scalar perturbations as well as for the
vector perturbations, analysis of the geodesics of light/massive particles, and
the accretion of matter onto the charged black hole solution.
