The quasinormal modes of the Reissner-Nordstr\"om de Sitter black hole for the massless Dirac fields are studied using the P\"oshl-Teller potential approximation. We find that the magnitude of the imaginary part of the quasinormal frequencies decreases as the cosmological constant or the orbital angular momentum increases, but it increases as the charge or the overtone number increases. An interesting feature is that the imaginary part is almost linearly related to the real part as the cosmological constant changes for fixed charge, and the linearity becomes better as the orbital angular momentum increases. We also prove exactly that the Dirac quasinormal frequencies are the same for opposite chirality.

  1. Revisiting the fermionic quasi-bound states around Schwarzschild black holes with improved analytic spectrum

    gr-qc 2025-01 conditional novelty 5.0 of 10

    Fermionic quasibound-state energies around Schwarzschild black holes are derived analytically with a first-order matching scheme and a higher-order angular correction that improves agreement with numerics.

  2. Scattering and Hawking Radiation from Einstein--Euler--Heisenberg--de Sitter Black Holes

    gr-qc 2026-06 unverdicted novelty 4.0 of 10

    Numerical scattering calculations for neutral scalar and Dirac fields on Einstein-Euler-Heisenberg-de Sitter black holes show that Euler-Heisenberg coupling raises barriers and shifts transmission frequencies upward w...

  3. Quasinormal Modes and Dynamical Evolution of Scalar Fields in the Einstein-Bumblebee Theory with a Cosmological Constant

    gr-qc 2025-02 conditional novelty 4.0 of 10

    For scalar perturbations of Einstein-Bumblebee black holes in de Sitter spacetime, increasing the Lorentz-violation parameter or the cosmological constant generally lowers the quasinormal mode frequency and damping rate.
