We examine the vacuum stability of gauge symmetry breaking in five dimensions, compactified on the $S_1/(\mathbb{Z}_2 \times \mathbb{Z}'_2)$ orbifold. We consider $SU(N)$, $Sp(N)$, $SO(2N)$ and $SO(2N+1)$ theories in the bulk, and provide an exhausti

In this article we assess the comprehension of physics concepts by Physical Science and Engineering students enrolled in their first semester at the University of Johannesburg (UJ), South Africa ($2022$). We employ different graphical measures to exp

In this paper, we present an enhanced semi-analytic method for calculating quasinormal excitation factors in the eikonal regime, specifically for Schwarzschild black holes. To achieve improved accuracy in our quasinormal mode computations, we extend

The findings discussed in "Apparent Horizons of the Thakurta Spacetime and the Description of Cosmological Black Holes" deviate from prior research, particularly our study in Phys. Rev. D 95, 084031 (2017). We clarify this inconsistency, which arises

We investigate the impact of higher dimensions on the properties of Schwarzschild-Tangherlini black holes, focusing on the photonsphere, black hole shadow, deflection angles, and quasinormal modes (QNMs). We find that these properties diminish as the

We consider constrained-degree percolation model on the hypercubic lattice \linebreak $\mathbb{L}^d=(\mathbb{Z}^d,\mathbb{E}^d)$. In this model, there exits a sequence $(U_e)_{e\in\mathbb{E}^d}$ of i.i.d. random variables with distribution $Unif([0,1

Expanding on the research on physics-informed neural networks (PINNs) to solve the eigenvalue problems in black hole (BH) perturbation theory, the supervised learning approach was investigated to solve the Regge-Wheeler and Teukolsky equations govern

This article discusses a three-year study (2020 - 2022) of dominant misconceptions (DMs) for a large cohort of first-year physics course students at the University of Johannesburg (UJ), South Africa. Our study considered pre-test scores on the Force
