Quasinormal modes of an electrically charged Kalb-Ramond black hole*
Year: 2026
Type: article
Abstract: Lorentz violation serves as a significant feature in many modified theories of gravity. In particular, spontaneous Lorentz violation induced by the Kalb-Ramond field has attracted considerable attention. Recently, an electrically charged black hole solution within the Kalb-Ramond framework was proposed. In this study, we investigate the odd-parity quasinormal modes of the resulting non-decouplable system of the gravitational and electromagnetic perturbations using both the matrix-valued continued fraction method and the matrix-valued direct integration method. Additionally, we develop a new approach to distinguish between different modes in such non-decouplable systems. An error analysis is performed, and the influence of Lorentz violation on the fundamental quasinormal modes is systematically analyzed within a suitable parameter range.
