Black-hole quasinormal modes have been the subject of much recent attention, with the hope that these oscillation frequencies may shed some light on the elusive theory of quantum gravity. We study analytically the asymptotic quasinormal spectrum of a charged scalar field in the (charged) Reissner–Nordström spacetime. We find an analytic expression for these black-hole resonances in terms of the black-hole physical parameters: its Bekenstein–Hawking temperature T BH , and its electric potential Φ. We discuss the applicability of the results in the context of black-hole quantization. In particular, we show that according to Bohr's correspondence principle the asymptotic resonance corresponds to a fundamental area unit Δ A = 4ℏln 2.
