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…
