Dynamical System Analysis Of Chameleon Mechanism in Brans-Dicke Scalar-Tensor Model
Azwar Sutiono, Agus Suroso, Freddy Permana Zen
We investigated the stability of the chameleon screening mechanism in the Brans-Dicke scalar-tensor model. We define a constraint on the Brans-Dicke parameter identifyin…
Minimal Length, Nuclear Matter, and Neutron Stars
I. Prasetyo, I. H. Belfaqih, A. B. Wahidin +2
In this paper, we employ one variant of the Generalized Uncertainty Principle (GUP) model, i.e., the Kempf-Mangano-Mann (KMM) model, and discuss the impact of GUP on the EoS of nuc…
Rotating black holes and exotic compact objects in the Kerr/CFT correspondence within Rastall gravity
Muhammad Fitrah Alfian Rangga Sakti, Agus Suroso, Anto Sulaksono +1
Quantum gravitational effects on the near horizon may alter the black hole's horizon drastically to be partially reflective, portrayed by a quantum membrane. With this modification…
(3+1)-Formulation for Gravity with Torsion and Non-Metricity II: The Hypermomentum Equation
Seramika Ariwahjoedi, Agus Suroso, F. P. Zen
In this article, we consider a special case of Metric-Affine f(R)-gravity for f(R) = R, i.e. the Metric-Affine General Relativity (MAGR). As a companion to the first article in the…
(3+1)-Formulation for Gravity with Torsion and Non-Metricity: The Stress-Energy-Momentum Equation
Seramika Ariwahjoedi, Agus Suroso, F. P. Zen
We derive the generalized Gauss-Codazzi-Mainardi (GCM) equation for a general affine connection with torsion and non-metricity. Moreover, we show that the metric compatibility and…

We show the generic non-extremal Kerr-Newman-NUT-AdS black holes are holographically dual to the hidden conformal field theories in two different pictures. The two pictures can be…

M. F. A. R. Sakti, A. M. Ghezelbash, A. Suroso +1
We find generators of the conformal symmetry for the class of Kerr-Newman-NUT-AdS black holes from the deformed scalar probe equation. We find two classes of solutions for the gene…

Getbogi Hikmawan, Jiro Soda, Agus Suroso +1
Recently, an interesting inflationary scenario, named Gauss-Bonnet inflation, is proposed by Kanti et al.~\cite{Kanti:2015pda,Kanti:2015dra}. In the model, there is no inflaton pot…
Vanishing Dimensions in Four Dimensional Cosmology with Nonminimal Derivative Coupling of Scalar Field
