Magnetized Reissner-Nordstrom-Taub-NUT spacetime and microscopic entropy
arXiv:2101.10302 · doi:10.1140/epjc/s10052-021-09643-2
Abstract
We present a novel solution describing magnetized spacetime outside a massive object with electric charge equipped with NUT parameter. To get the solution, we employ the Ernst magnetization to the Reissner-Nordstrom-Taub-NUT spacetime as the seed. After discussing some physical aspects of the spacetime, we show that the extremal entropy of a magnetized Reissner-Nordstrom-Taub-NUT black hole can be reproduced by using the Cardy formula.
