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…
