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 generat…
Spectral and Dynamical Properties of the Fractional Nonlinear Schrödinger Equation under Harmonic Confinement
R. Kusdiantara, M. F. Adhari, H. A. Mardi +2
We investigate the spectral and dynamical properties of the fractional nonlinear Schrödinger (fNLS) equation with harmonic confinement. In this setting, the classical Laplacian is…
In-band supratransmission in nonlinear flat band lattices
R. Kusdiantara, M. Wijaya, M. F. Adhari +1
Studying wave propagation in nonlinear discrete systems is essential for understanding energy transfer in lattices. While linear systems prohibit wave propagation within the natura…
Exponential asymptotics of dark and bright solitons in the discrete nonlinear Schrödinger equation
Farrell Theodore Adriano, Abrari Noor Hasmi, Rudy Kusdiantara +1
We investigate the existence and linear stability of solitons in the nonlinear Schrödinger lattices in the strong coupling regime. Focusing and defocusing nonlinearities are consi…
Nonlinear states of the conservative complex Swift-Hohenberg equation
Rudy Kusdiantara, Hadi Susanto
We consider the conservative complex Swift-Hohenberg equation, which belongs to the family of nonlinear fourth-order dispersive Schrödinger equations. In contrast to the well-stud…
