Kerr-NUT Thermodynamics: Misner Strings and Nut Charges
Mohamed Tharwat, Adel Awad
Using the thermodynamic approach introduced in e-Print: 2206.09124 [hep-th] to the case of Kerr-NUT solution, we demonstrate the existence of a new conserved quantity that is dual…
Bianchi IX dynamics with a phantom field
Adel Awad, Dmitry Chirkov, Alexey Golovnev +1
We consider Bianchi IX dynamics of a Universe filled with a massless phantom field. Such an exotic matter source enables regimes impossible in vacuum or with a standard scalar fiel…
Gauss-Bonnet Gravity and Spacetime Singularities
Tariq Allaithy, Adel Awad, Mohamed Hany Radwan +1
We investigate the effect of higher-order curvature terms, specifically Gauss-Bonnet terms, on spacetime singularities in five dimensions. For FLRW cosmologies, we demonstrate that…
Dyonic Taub-NUT-AdS Black Branes: Thermodynamics and Phase Diagrams
Amr AlBarqawy, Adel Awad, Esraa Elkhateeb +1
Motivated by the recent developments in the thermodynamics of Taub-NUT spaces and the absence of Misner strings in Taub-NUT solutions with flat horizons, we investigated the phase…
Dyonic Taub-NUT-AdS Spaces: Phase Structures of all Horizon Geometries
Mohamed Tharwat, Amr AlBarqawy, Adel Awad +1
We study phase structures of Lorentzian Dyonic Taub-NUT-AdS spacetimes for different horizon geometries, which are spherical, flat, and hyperbolic. We check the consistency of our…
Rotating charged AdS solutions in quadratic gravity
A. M. Awad, G. G. L. Nashed, W. El Hanafy
We present a class of asymptotically anti-de Sitter charged rotating black hole solutions in gravity in -dimensions, where . These solutions are nontrivial…
Phase Portraits of general f(T) Cosmology
A. Awad, W. El Hanafy, G. G. L. Nashed +1
We use dynamical system methods to explore the general behaviour of cosmology. In contrast to the standard applications of dynamical analysis, we present a way to transform…
Constant-roll Inflation in Teleparallel Gravity
A. Awad, W. El Hanafy, G. G. L. Nashed +2
We investigate in detail the implications of the constant-roll condition on the inflationary era of a scalar field coupled to a teleparallel gravity. The resulting cosmologi…
-dimensional charged Anti-de-Sitter black holes in gravity
A. M. Awad, S. Capozziello, G. G. L. Nashed
We present a -dimensional charged Anti-de-Sitter black hole solutions in gravity, where and . These solutions are characterized by flat or cylindr…
