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…
