On Modeling Anisotropic Quark Stars: The Role of Anisotropy in Radial Oscillation Spectra

G. Panotopoulos

We model the compact object Cen X-3, which is considered to be a good strange quark star candidate of known mass and radius, incorporating a negative anisotropic factor, and we com…

Slowly rotating condensate dark stars beyond the mean-field approximation

Grigoris Panotopoulos, Ángel Rincón, Ángel Rincón +1

We investigate rotational properties and universal relations of slowly rotating Bose-Einstein condensate dark stars in the context of General Relativity, both at the mean-field lev…

Radial oscillations of quark stars in light of current astrophysical constraints: A comparative study

G. Panotopoulos, A. Rincon, I. Lopes

We investigate the structural and oscillatory properties of isotropic strange quark stars within General Relativity, focusing on three physically motivated equations of state: the…

Black hole physics within gravity: Quasi-normal spectra and greybody factors

Ángel Rincón, Grigoris Panotopoulos

We investigate several astrophysical motivated properties of a four-dimensional black hole solution in the framework of gravity. The model is characterized by a single addit…

Quantum correlations and coherence in a two-qubit anisotropic under magnetic field

Ahmed Jellal, Pablo Díaz, David Laroze

We study thermal quantum correlations and coherence in Heisenberg model with anisotropic interactions under a uniform magnetic field . Using concurrence , local quantu…

Magnetic control of electron scattering in silicene quantum dots

Mohamed El Azar, Elmustapha Feddi, Pablo Díaz +2

The Klein tunnel effect phenomenon makes it impossible to permanently confine charge carriers in massless nanostructures. However, applying a constant magnetic field allows these e…
