[HTML][HTML] Fractional holographic dark energy

O Trivedi, A Bidlan, P Moniz - Physics Letters B, 2024 - Elsevier
Holographic dark energy theories present a fascinating interface to probe late-time
cosmology, as guided by contemporary ideas about quantum gravity. In this work, we …

Schwarzschild spacetime in fractal dimensions: Deflection of light, supermassive black holes and temperature effects

RA El-Nabulsi, W Anukool - Modern Physics Letters A, 2024 - World Scientific
In this paper, we construct a Schwarzschild metric in the fractal dimension based on fractal
calculus, and we study the deflection of light near the sun. It was observed that the new …

Fractional mimetic dark matter: A fractional action-like variational approach

RA El-Nabulsi, CFL Godinho, IV Vancea - Modern Physics Letters A, 2024 - World Scientific
In this paper, we propose a nonlocal extension of the mimetic dark matter model based on
the FALVA implementation of fractional calculus. Our primary objective to explore how …
