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…
Spontaneous symmetry-breaking in the nonlinear Schrödinger equation on star graphs with inhomogeneities
Rahmi Rusin, Hadi Susanto
We investigate the nonlinear Schrödinger equation on a three-edge star graph, where each edge contains a linear localized inhomogeneity in the form of a Dirac delta linear potentia…
Symmetry breaking bifurcations in the NLS equation with an asymmetric delta potential
Rahmi Rusin, Robert Marangell, Hadi Susanto
We consider the NLS equation with a linear double well potential. Symmetry breaking, i.e., the localisation of an order parameter in one of the potential wells that can occur when…
Variational approximations of soliton dynamics in the Ablowitz-Musslimani nonlinear Schrödinger equation
Rahmi Rusin, Rudy Kusdiantara, Hadi Susanto
We study the integrable nonlocal nonlinear Schrödinger equation proposed by Ablowitz and Musslimani, that is considered as a particular example of equations with parity-time ($\mat…
Variational approximations using Gaussian ansatz, false instability, and its remedy in nonlinear Schrödinger lattices
Rahmi Rusin, Rudy Kusdiantara, Hadi Susanto
We study the fundamental lattice solitons of the discrete nonlinear Schrödinger (DNLS) equation and their stability via a variational method. Using a Gaussian ansatz and comparing…
