Tilt and Tensor-to-Scalar Ratio in Multi-Scalar Field Inflation: Non-Sum-Separable Case
Fereshteh Felegary, Seyed Ali Hosseini Mansoori, Tahere Fallahi Serish +1
The canonical multi-scalar field inflation where the kinetic and potential terms are sum-separable is ruled out by the current observations for the chaotic-type potential $V=\sum_{…
Stability of Extremal Black Holes and Weak Cosmic Censorship Conjecture in Kiselev Spacetime
Ankit Anand, Anshul Mishra, Phongpichit Channuie
In this study, we investigate the Weak Gravity Conjecture (WGC) and Weak Cosmic Censorship Conjecture (WCCC) for a quantum-corrected Reissner-Nordström Anti-de Sitter (RN-AdS) blac…
Kiselev-inspired Wormholes
Jureeporn Yuennan, Piyachat Panyasiripan, Phongpichit Channuie
In this study, we investigate traversable wormholes inspired by the Kiselev framework, which extends classical black hole solutions by incorporating anisotropic fluids. These exoti…
Charged Wormhole Solutions in 4D Einstein-Gauss-Bonnet Gravity
Piyachat Panyasiripan, Fereshteh Felegary, Phongpichit Channuie
In the present work, we construct models of static wormholes within the framework of 4-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity an (an)isotropic energy momentum tensor (E…
Cosmological dynamics of interacting dark energy and dark matter in gravity
Gaurav N. Gadbail, Simran Arora, Phongpichit Channuie +1
In this work, we explore the behavior of interacting dark energy and dark matter within a model of gravity, employing a standard framework of dynamical system analysis. We c…
Gravity Rainbow Effects on Higher Curvature Modification of R2 inflation
Jureeporn Yuennan, Phongpichit Channuie, Davood Momeni
In this work, we study several extensions of the higher curvature modification of inflation in the context of gravity's rainbow. We modify the model by adding a…
