A comparison of remnants in noncommutative Bardeen black holes | | S. Hamid Mehdipour

18 Apr 2016 | | Abstract: | We derive the mass term of the Bardeen metric in the presence of a
noncommutative geometry induced minimal length. In this setup, the proposal of
a stable black hole remnant as a candidate to store information is confirmed.
We consider the possibility of having an extremal configuration with one
degenerate event horizon and compare different sizes of black hole remnants. As
a result, once the magnetic charge $g$ of the noncommutative Bardeen solution
becomes larger, both the minimal nonzero mass $M_0$ and the minimal nonzero
horizon radius $r_0$ get larger. This means, subsequently, under the condition
of an adequate amount of $g$, the three parameters $g$, $M_0$, and $r_0$ are in
a connection with each other linearly. According to our results, a
noncommutative Bardeen black hole is colder than the noncommutative
Schwarzschild black hole and its remnant is bigger, so the minimum required
energy for the formation of such a black hole at particle colliders will be
larger. We also find a closely similar result for the Hayward solution. | | Source: | arXiv, 1604.6272 | | Services: | Forum | Review | PDF | Favorites | |
