Multiprecision computation of bright and dark solitons in the discrete nonlinear Schrödinger equation
Rudy Kusdiantara, Farrell T. Adriano, Hadi Susanto
We study the spectral stability of bright and dark solitons in the discrete nonlinear Schrödinger (DNLS) equation using multiprecision arithmetic. The eigenvalues governing stabili…
Snakes on Lieb lattice
R. Kusdiantara, F. T. Akbar, N. Nuraini +2
We consider the discrete Allen-Cahn equation with cubic and quintic nonlinearity on the Lieb lattice. We study localized nonlinear solutions of the system that have linear multista…
How many can you infect? Simple (and naive) methods of estimating the reproduction number
H. Susanto, V. R. Tjahjono, A. Hasan +5
This is a pedagogical paper on estimating the number of people that can be infected by one infectious person during an epidemic outbreak, known as the reproduction number. Knowing…
A new estimation method for COVID-19 time-varying reproduction number using active cases
A. Hasan, H. Susanto, V. R. Tjahjono +4
We propose a new method to estimate the time-varying effective (or instantaneous) reproduction number of the novel coronavirus disease (COVID-19). The method is based on a discrete…
