Dynamics of charged test particles around quantum-corrected Schwarzschild black holes

We investigate neutral and charged test particles’ motions around quantum-corrected Schwarzschild black holes immersed in an external magnetic field. Taking the innermost stable circular orbits of neutral timelike particles into account, we find that the black holes can mimic different ranges of the Kerr black hole’s spin | a / M | from 0.15 to 0.99. Our analysis of charged test particles’ motions suggests that the values of the angular momentum...
