Constant-roll inflation with a complex scalar field
Ramón Herrera, Mehdi Shokri, Jafar Sadeghi
We consider inflation with a constant rate of rolling in which a complex scalar field plays the role of inflaton during the inflationary epoch. We implement the inflationary analys…
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…
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…
Traversable wormhole in logarithmic gravity by various shape and redshift functions
J. Sadeghi, M. Shokri, S. Noori Gashti +2
We study the traversable wormhole solutions for a logarithmic corrected model by considering two different statements of shape and redshift functions. We calcu…
Constant-roll inflation compared with Cosmic Microwave Background anisotropies and swampland criteria
Mehdi Shokri, Mohammad Reza Setare, Salvatore Capozziello +1
Inflationary models derived from gravity, where the scalaron rolls down with a constant rate from the top to the minimum of the effective potential, are considered. Specific…
Constant-roll inflation from a fermionic field
M. Shokri, J. Sadeghi, M. R. Setare
We study the inflationary period driven by a fermionic field which is non-minimally coupled to gravity in the context of the constant-roll approach. We consider the model for a spe…
Nonminimal coupling inflation with constant slow roll
Mehdi Shokri, Jafar Sadeghi, Mohammad Reza Setare +1
We study a single field inflationary model modified by a non-minimal coupling term between the Ricci scalar and the scalar field in the context of constant-roll inflation.…
The generalized and in non-minimal constant-roll inflation
Mehdi Shokri, Jafar Sadeghi, Mohammad Reza Setare
In the present work, we consider the non-minimal coupling inflationary model in the context of the constant-roll idea which is investigated by the first-order formalism. We attempt…
A Revision to the Issue of Frames by Non-minimal Large Field Inflation
M. Shokri
We present an extended study of inflationary models that inflaton field is non-minimally coupled with gravity. We study parameters space of the models up to the second (and in some…
