On the constant roll complex scalar field inflationary models
Ali Mohammadi, Nahid Ahmadi, Mehdi Shokri
In this paper we wish to point out the possibility of using a complex scalar field in a constant roll inflationary model, as needed for observational viability. We extend the idea…
Slow-roll inflation in non-metric gravity
Salvatore Capozziello, Mehdi Shokri
We discuss the cosmological inflation in the context of non-metric gravity, where is the non-metric scalar. After introducing conformal transformations for gravit…
G-constant-roll inflation
Ramon Herrera, Jafar Sadeghi, Mehdi Shokri
The constant-roll inflation in the context of Galilean inflation or G-inflation is analyzed. By considering a coupling function for the model of G-inflati…
RPS Thermodynamics of Taub-NUT AdS Black Holes in the Presence of Central Charge and the Weak Gravity Conjecture
Jafar Sadeghi, Mehdi Shokri, Saeed Noori Gashti +1
We study the thermodynamics of the Taub-NUT AdS black holes by Visser holographic method using AdS radius as a constant parameter under the restricted phase space approach. Instead…
Anisotropic constant-roll inflationary scenario with complex quintessence field and swampland conjectures
Jafar Sadeghi, Saeed Noori Gashti, Mehdi Shokri
In this paper, with the presence of swampland conjecture, we use the complex form of a scalar field and investigate the anisotropic constant-roll of an inflationary scenario. Recen…
Weak Gravity Conjecture from Conformal Field Theory: A Challenge from Hyperscaling Violating and Kerr-Newman-AdS Black Holes
Jafar Sadeghi, Mehdi Shokri, Mohammad Reza Alipour +1
We search for a possible relation between weak gravity conjecture and conformal field theory in the hyperscaling violating and Kerr-Newman-AdS black holes. We deal with the critica…
