Chargeless massive scalar fields are studied in the spacetime of Born–Infeld dilaton black
holes (BIDBHs). We first separate the massive covariant Klein–Gordon equation into radial …

In a seminal paper, Alcubierre showed that Einstein's theory of general relativity appears to
allow a super-luminal motion. In the present study, we use a recent eternal-warp-drive …

In Schwarzschild acoustic black hole (SABH) spacetime, we investigate the wave dynamics
for the fermions. To this end, we first take into account the Dirac equation in the SABH by …

Modifying a method by Horowitz and Hubeny for asymptotically anti-de Sitter black holes, we
establish the classical stability of the quasinormal modes of the de Sitter spacetime …

We numerically calculate the quasinormal frequencies of the Klein-Gordon and Dirac fields
propagating in a two-dimensional asymptotically anti-de Sitter black hole of the dilaton …

In this paper the question of the emission of fermions in the process of dilaton black hole
evolution and its characteristics for different dilaton coupling constants α are studied. The …

We calculate exactly the quasinormal frequencies of Klein–Gordon and Dirac test fields
propagating in 2D uncharged Achucarro–Ortiz black hole. For both test fields we study …

External non-minimally coupled scalar and spinor field perturbations have been studied in a
(1+ 1) dimensional dilatonic blackhole spacetime (Mandal et al. in Mod Phys Lett A 6: 1685 …

In this article, we study the stability of black hole solutions found in the context of dilatonic
Horava–Lifshitz gravity in 1+ 1 1+ 1 dimensions by means of the quasinormal modes …

In the zero momentum limit we exactly calculate the quasinormal frequencies of the massive
Dirac field propagating in a Lifshitz black brane. Our results are an extension of those for the …
