Heun Spectrum, Threshold Hierarchy, and One-Loop Quantum Mass of the Christ--Lee Kink
Mulyanto, Afif Jalu Pradipta, Ardian Nata Atmaja +1
We study the fluctuation spectrum and renormalized one-loop quantum mass of the Christ--Lee kink over the full positive range of its deformation parameter. The fluctuation equation…
Global existence of classical static solutions of four dimensional Einstein-Klein-Gordon system
Mirda Prisma Wijayanto, Emir Syahreza Fadhilla, Fiki Taufik Akbar +1
In this paper we prove the global existence of classical static solutions of Einstein gravitational theory coupled to a real scalar field where the spacetime admits spherically sym…
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 Lugiato-Lefever model from a damped driven equation
Fiki T. Akbar, Bobby E. Gunara, Hadi Susanto
The Lugiato-Lefever equation is a damped and driven version of the well-known nonlinear Schrödinger equation. It is a mathematical model describing complex phenomena in dissipative…
Local and Global Existence of Solutions to Scalar Equations on Spatially Flat Universe as a Background with Non-minimal Coupling
Fiki T. Akbar, Bobby E. Gunara, Muhammad Iqbal +1
We prove the wellposedness of scalar wave equations on spatially flat universe as a background with nonminimal coupling with the scalar potential turned on by introducing the -o…
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…
