Stability of Einstein and de Sitter Universes in the Quadratic Theory of Modified Gravity
Mudhahir Al Ajmi
We consider the Einstein static and the de Sitter universe solutions and examine their instabilities in a subclass of quadratic modified theories for gravity. This modification pro…
Chaos in balanced and unbalanced holographic s+p superconductors
Davood Momeni, Nayereh Majd, Morteza Mohammadzaheri +2
In this work, we propose a toy model for a mixture of superconductors with competitive s and p modes using gauge/gravity duality. We demonstrate that the model undergoes phase tran…
Curvaton: Perturbations and reheating
Mohit Kumar Sharma, Kairat Myrzakulov, Mudhahir Al Ajmi
We study chaotic and runaway potential inflationary models in the curvaton scenario. In particular, we address the issue of large tensor-to-scalar ratio and red-tilted spectrum in…
On Nash theory of gravity with matter contents
Phongpichit Channuie, Davood Momeni, Mudhahir Al Ajmi
Although it was proved that the Nash theory doesn't have classical Einstein limits, it has been proven to be formally divergent free and considered to be of interest in constructin…
Noether symmetry in the Nash theory of gravity
Phongpichit Channuie, Davood Momeni, Mudhahir Al Ajmi
This paper deals with the study of Bianchi type-I universe in the context of Nash gravity by using the Noether symmetry approach. We shortly revisit the Nash theory of gravity. We…
Holographic Entanglement Entropy, Complexity, Fidelity Susceptibility and Hierarchical UV/IR Mixing Problem in $AdS_2/\mbox{open strings}$
Kazuharu Bamba, Davood Momeni, Mudhahir Al Ajmi
In this paper, we will compute the holographic complexity (dual to a volume in AdS), holographic fidelity susceptibility and the holographic entanglement entropy (dual to an area i…
