Topologically Protected Spatially Localized Modes: An Easy Experimental Realization of the Su--Schrieffer--Heeger Model
L. Q. English, A. Halchenko, F. Palmero
In this paper, we review the basic concepts of topologically protected edge modes using the Su Schrieffer Heeger (SSH) model, originally introduced to describe electrical conductiv…
Scattering-induced splitting of solitons in the discrete NLS equation with saturable nonlinearity
J. F. Tsoplefack, F. Palmero, J. Cuevas-Maraver +2
We study systematically the scattering of solitons on localized impurities in the discrete nonlinear Schrödinger (DNLS) equation with a saturable nonlinearity. We show that, apart…
Discrete embedded solitary waves and breathers in one-dimensional nonlinear lattices
Faustino Palmero, Mario I. Molina, Jesús Cuevas-Maraver +1
For a one-dimensional linear lattice, earlier work has shown how to systematically construct a slowly-decaying linear potential bearing a localized eigenmode embedded in the contin…
Nonlinear edge modes in a honeycomb electrical lattice near the Dirac points
F. Palmero, L. Q. English, J. Cuevas-Maraver +1
We examine - both experimentally and numerically - a two-dimensional nonlinear driven electrical lattice with honeycomb structure. Drives are considered over a range of frequencies…
Experimental and numerical observation of dark and bright discrete solitons in the band-gap of a diatomic-like electrical lattice
F. Palmero, L. Q. English, Xuan-Lin Chen +3
We observe dark and bright intrinsic localized modes (ILMs) or discrete breathers (DB) experimentally and numerically in a diatomic-like electrical lattice. The generation of dark…
Impulse-induced localized nonlinear modes in an electrical lattice
F. Palmero, J. Cuevas-Maraver, L. Q. English +1
Intrinsic localized modes, also called discrete breathers, can exist under certain conditions in one-dimensional nonlinear electrical lattices driven by external harmonic excitatio…
