Dynamics of charged particles around weakly magnetized loop quantum gravity black hole

Abstract

In this article, we have studied the dynamics of electrically and magnetically charged particles in the spacetime of loop quantum gravity-corrected Schwarzschild black hole (LQGBH). We consider the loop quantum gravity (LQG) immersed in an external asymptotically uniform magnetic field. The effects of LQG spacetime on dynamics of the particles is studied. We have discussed the circular orbits of the particles about the central object and studied the dependence of the inner stable circular orbits (ISCOs) on the magnetic coupling parameter and the black hole parameters. The synchrotron radiations coming out of the charged particle (accelerated by electromagnetic forces Coulomb and Lorentz) in the surrounding of the magnetized LQGBH is analysed. We have also studied the effects of LQG parameters on the specific angular momentum, energy and ISCOs. We calculated the minimum energy and angular momentum of the magnetized particles required to move in the ISCO. We did this analysis by first calculating the magnetic coupling parameter of the LQGBH spacetime. We have also investigated the collision of neutral, electrically and magnetically charged particles and their centre of mass energy. It is observed that magnetic field around black hole increases the particle acceleration around LQGBH.
