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…
Supratransmission in Lattices with Purely Nonlinear Coupling
Defri Ahmad, Tae-Yeon Kim, Andreas Schiffer +2
Supratransmission is examined in nonlinear lattices with purely nonlinear coupling, extending the phenomenon to systems that lack a linear pass band. In contrast to standard lattic…
Dynamics and stabilization of topological edge solitons in driven-damped nonlinear SSH lattices
Adrianus Yosia, Rahmi Rusin, Rudy Kusdiantara +1
We study topological edge solitons in a nonlinear Su--Schrieffer--Heeger (SSH) lattice subject to parametric driving and linear damping. Starting from a vertically driven pendulum…
Pearl supratransmission in a boundary-driven two-dimensional nonlinear Schrödinger equation with a hole
Rudy Kusdiantara, Hadi Susanto
We investigate energy supratransmission in a boundary-driven two-dimensional nonlinear Schrödinger equation with a central hole. Harmonic forcing with azimuthal modulation generate…
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…
Solitons in a chain of charge-parity-symmetric dimers
O. B. Kirikchi, B. A. Malomed, N. Karjanto +2
We consider an array of dual-core waveguides, which represent an optical realization of a chain of dimers, with an active (gain-loss) coupling between the cores, opposite signs of…
