abstract

We have studied scalar perturbations as well as fermion perturbations in pure de Sitter space-times. For scalar perturbations we have showed that well-defined quasinormal modes can exist provided that the mass of scalar field $m>\frac{d-1}{2l}$. The quasinormal frequencies of fermion perturbations in three and four dimensional cases have also been presented. We found that different from other dimensional cases, in three dimensional pure de Sitter spacetime there is no quasinormal mode for the s-wave. This interesting difference caused by the spacial dimensions is true for both scalar and fermion perturbations.

  1. Scalar fields and 3D Flat Space Cosmologies

    hep-th 2025-06 reject novelty 7.0 of 10

    A direct bulk derivation of scalar quasi-normal modes in 3D flat space cosmologies is presented, using a hard-wall boundary condition and complex momenta, together with one-loop partition functions computed in simplif...

  2. Scalar perturbations and strong cosmic censorship in a regular ABGB-de Sitter black hole spacetime

    gr-qc 2026-07 conditional novelty 6.0 of 10

    In regular ABGB-de Sitter black holes, near-extremal scalar perturbations decay fast enough (β>1/2) to violate strong cosmic censorship, and adding scalar mass can push the regularity parameter past β=1.

  3. Fermion quasinormal modes on modified RN background

    gr-qc 2025-07 conditional novelty 6.0 of 10

    Charged massless fermion quasinormal modes in a noncommutatively deformed Reissner-Nordström black hole show a linear, azimuthal-quantum-number-dependent splitting of the complex mode frequencies.

    The paper derives eikonal quasinormal mode frequencies and shock-wave switchback delays in Schwarzschild-de Sitter for arbitrary mass, using static-sphere observers and reflecting boundary conditions.

    For scalar fields with non-minimal derivative coupling on Reissner-Nordström-de Sitter black holes, strong cosmic censorship is violated only when the ratio β exceeds 3/2 instead of 1/2, and small near-extremal black ...
