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

Abstract 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 rang...
