Analytical Criteria for Black Hole Instability in Non-Minimally Coupled Scalar-Tensor Theories
Majid Karimabadi, Davood Mahdavian Yekta, S. A. Alavi
In this paper, we show that the robustness of black hole stability is not preserved when perturbations are subjected to critical values of the coupling constant in two non-minimall…

Scalar field perturbations in Non-commutative Schwarzschild spacetime: Comparative analysis and Upper bound on non-commutativity
Majid Karimabadi, Davood Mahdavian Yekta, S. A. Alavi
This work presents a comparative analysis of the quasi-normal modes and ringdowns of scalar field perturbations in the non-commutative Schwarzschild black hole spacetime, focusing…

Note on WAdS black holes in extended BHT gravity
Davood Mahdavian Yekta
In this letter, we study a holographic diffeomorphism invariant higher-derivative extension of Bergshoeff-Hohm-Townsend (BHT) cosmological gravity in the context of Wald's formalis…
