General Couplings of Four Dimensional Maxwell-Klein-Gordon System: Global Existence
Mulyanto, Fiki Taufik Akbar, Bobby Eka Gunara
In this paper, we consider the multi component fields interactions of the complex scalar fields and the electromagnetic fields (Maxwell-Klein-Gordon system) on four dimensional Min…
Justification of the discrete nonlinear Schrödinger equation from a parametrically driven damped nonlinear Klein-Gordon equation and numerical comparisons
Y. Muda, F. T. Akbar, R. Kusdiantara +2
We consider a damped, parametrically driven discrete nonlinear Klein-Gordon equation, that models coupled pendula and micromechanical arrays, among others. To study the equation, o…
Reduction of damped, driven Klein-Gordon equations into a discrete nonlinear Schrödinger equation: justification and numerical comparisons
Yuslenita Muda, Fiki T. Akbar, Rudy Kusdiantara +2
We consider a discrete nonlinear Klein-Gordon equations with damping and external drive. Using a small amplitude ansatz, one usually approximates the equation using a damped, drive…
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…
Existence of Static Dyonic Black Holes in Supergravity With Finite Energy
Fiki Taufik Akbar, Bobby Eka Gunara
We prove the existence and the uniqueness of the static dyonic black holes in four dimensional supergravity theory coupled vector and scalar multiplets. We set the near-horiz…
