Rotating traversable wormholes and particle dynamics in gravity
G. G. L. Nashed, Waleed El Hanafy, Amare Abebe +2
Traversable wormholes are among the most interesting solutions of gravitational theories, but within General Relativity they generally require exotic matter violating the null ener…
Buchdahl limit of compact stars in presence of Weyl anomaly
Waleed El Hanafy, G. G. L. Nashed
We setup an anisotropic compact star model in presence of Weyl ``trace" anomaly. We derive an exact interior solution which determines the contribution of the vacuum trace anomaly.…
Thermodynamical correspondence of gravity in Jordan and Einstein frames
G. G. L. Nashed, W. El Hanafy, S. D. Odintsov +1
We study the thermodynamical aspects of gravity in the Jordan and the Einstein frame, and we investigate the corresponding equivalence of the thermodynamical quantities in t…
Charged rotating black holes coupled with nonlinear electrodynamics Maxwell field in the mimetic gravity
G. G. L. Nashed, W. El Hanafy, Kazuharu Bamba
In mimetic gravity, we derive -dimension charged black hole solutions having flat or cylindrical horizons with zero curvature boundary. The asymptotic behaviours of these black…
Lorenz Gauge Fixing of Teleparallel Cosmology
W. El Hanafy, G. G. L. Nashed
In teleparallel gravity, we apply Lorenz type gauge fixing to cope with redundant degrees of freedom in the vierbein field. This condition is mainly to restore the Lorentz symmetry…
