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-…
Global Existence and Singularity Formation of Classical Solutions in Einstein-Skyrme System
Emir Syahreza Fadhilla, Ardian Nata Atmaja, Bobby Eka Gunara
In this paper, we elucidate the problem of gravitating Skyrmion governed by field equations of the Einstein-Skyrme system with no potential term in the Bondi coordinate. The spheri…
Static Black Holes of Higher Dimensional Einstein-Skyrme System with General Couplings
Bobby Eka Gunara, Emir Syahreza Fadhilla, Ardian Nata Atmaja
We construct hairy static black holes of higher dimensional general coupling Einstein-Skyrme theories with the scalar potential turned on and the cosmological constant is non-posit…
Axisymmetric Stationary Spacetimes of Constant Scalar Curvature in Four Dimensions
Rosikhuna F. Assafari, Emir S. Fadhilla, Bobby E. Gunara +2
In this paper we construct a special class of four dimensional axisymmetric stationary spacetimes whose Ricci scalar is constant but not Einstein. We find that this solution has a…
