Preliminary study on the impact of stress-energy tensor compared to scalar field in Nonminimal Derivative model
Ilham Prasetyo, Bobby Eka Gunara, Agus Suroso
In this article, we report the results of comparing the effect of using trace of stress-energy tensor versus real-valued scalar field in Nonminimal Derivative Coupling gravitation…
Cosmic Inflation From Fluctuating Baby-Skyrme Brane
Emir Syahreza Fadhilla, Bobby Eka Gunara, Agus Suroso +1
In this work, we explore the inflationary dynamics induced by small fluctuations on the Skyrme brane, characterized by a time-dependent perturbative function . In the low-…
Some Cosmological Consequences of Higher Dimensional Klein-Gordon-Rastall Theory
Tegar Ari Widianto, Ahmad Khoirul Falah, Agus Suroso +2
Using dynamical system analysis, we investigate some cosmological consequences of Rastall gravity coupled to a scalar field (called the Klein-Gordon-Rastall theory) with exponentia…
