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…
Role of universal function of the nuclear proximity potential: A systematic study on the alpha-decay of heavy/super-heavy nuclei and α-induced reactions
S. Mohammadi, R. Gharaei, S. A. Alavi
The idea of the universal function is fundamental advantage of proximity potential model. We present a systematic study of the role of universal function of the proximity potential…
The nuclear surface diffuseness effects on the alpha decay of heavy and super heavy nuclei
S. Mohammadi, R. Gharaei, S. A. Alavi
We select 300 different parent nuclei in the range Z from 64 to 106. The proximity potentials Zhang 2013 and Guo 2013 are employed to calculate the nuclear potential. The influence…
