Some Aspects of Spherical Symmetric Extremal Dyonic Black Holes in 4d N=1 Supergravity

Bobby E. Gunara, Freddy P. Zen, Fiki T. Akbar +2

In this paper we study several aspects of extremal spherical symmetric black hole solutions of four dimensional N=1 supergravity coupled to vector and chiral multiplets with the sc…

Kaluza-Klein two-brane-worlds cosmology at low energy

S. Feranie, Arianto, Freddy P. Zen

We study two -dimensional branes embedded in -dimensional spacetime. Using the gradient expansion approximation, we find that the effective theory is described by $(4…

Modified Gravitational Equations on Braneworld with Lorentz Invariant Violation

A. Arianto, Freddy P. Zen, Bobby E. Gunara

The modified gravitational equations to describe a four-dimensional braneworld in the case with the Lorentz invariant violation in a bulk spacetime is presented. It contains a trac…

N=1 Supergravity BPS Domain Walls on Kähler-Ricci Soliton

Bobby E. Gunara, Freddy P. Zen, Arianto

This paper provides a study of some aspects of flat and curved BPS domain walls together with their Lorentz invariant vacua of four dimensional chiral N=1 supergravity. The scalar…

Cosmological evolution of interacting dark energy in Lorentz violation

Freddy P. Zen, Arianto, Bobby E. Gunara +2

The cosmological evolution of an interacting scalar field model in which the scalar field interacts with dark matter, radiation, and baryon via Lorentz violation is investigated. W…

Attractor Solutions in Lorentz Violating Scalar-Vector-Tensor Theory

Arianto, Freddy P. Zen, Triyanta +1

We investigate properties of attractors for scalar field in the Lorentz violating scalar-vector-tensor theory of gravity. In this framework, both the effective coupling and potenti…
