Coulomb Sectors and Scattering for Maxwell-Higgs Fields on Schwarzschild and Slowly Rotating Kerr Backgrounds
Bobby Eka Gunara, Mulyanto, Fiki Taufik Akbar
We develop a small-data Maxwell--Higgs theory on Schwarzschild and slowly rotating Kerr black-hole exteriors for gauge-invariant nonnegative self-interactions near the trivial vacu…
Isotropic and Anisotropic Radiating Gravastars with Various Matter Types of Thin Shell and Interior
Hasan Al-Asy'ari, Fiki Taufik Akbar, Bobby Eka Gunara
In this paper, we investigate models of radiating gravastars with both isotropic and anisotropic interiors, incorporating various types of thin shell matter. For the isotropic inte…
Classical Solutions of Higher Dimensional Einstein-Maxwell-Higgs System With Nontrivial Potential: Global Existence and Completeness
Mirda Prisma Wijayanto, Fiki Taufik Akbar, Bobby Eka Gunara
We study the Cauchy problem of higher dimensional Einstein-Maxwell-Higgs system in the framework of Bondi coordinates. As a first step, the problem is reduced to a single first-ord…
Gravitational Collapse in Higher-Dimensional Rastall Gravity with and without Cosmological Constant
Golfin Ekatria, Andy Octavian Latief, Fiki Taufik Akbar +1
We consider a spherically symmetric homogeneous perfect fluid undergoing a gravitational collapse to singularity in the framework of higher-dimensional Rastall gravity in the cases…
Global Existence and Completeness of Classical Solutions in Higher Dimensional Einstein-Klein-Gordon System
Mirda Prisma Wijayanto, Fiki Taufik Akbar, Bobby Eka Gunara
In this paper we study the global existence and completeness of classical solutions of gravity coupled a scalar field system called Einstein-Klein-Gordon system in higher dimension…
Static Spacetimes In Higher Dimensional Scalar-Torsion Theories With Non-Minimal Derivative Coupling
Bobby E. Gunara, Mulyanto, Rahmat H. Alineng +2
In this paper we consider a class of static spacetimes in higher dimensional () scalar-torsion theories with non-minimal derivative coupling and the scalar potential turne…
Effective spacetime geometry of graviton condensates in gravity
Andy Octavian Latief, Fiki Taufik Akbar, Bobby Eka Gunara
We consider a model of Bose-Einstein condensate of weakly interacting off-shell gravitons in the regime that is far from the quantum critical point. Working in static spherically s…
