Nonlinear edge modes in a honeycomb electrical lattice near the Dirac points
(Elsevier, 2020-06)
We examine - both experimentally and numerically - a two-dimensional nonlinear driven electrical lattice with honeycomb structure. Drives are considered over a range of frequencies both outside (below and above) and ...

We examine - both experimentally and numerically - a two-dimensional nonlinear driven electrical lattice with honeycomb structure. Drives are considered over a range of frequencies both outside (below and above) and ...

Multibreather and vortex breather stability in Klein–Gordon lattices: equivalence between two different approaches
(2011)
In this work, we revisit the question of stability of multibreather configurations, i.e. discrete breathers with multiple excited sites at the anti-continuum limit of uncoupled oscillators. We present two methods that yield ...

Multibreathers in Klein-Gordon chains with interactions beyond nearest neighbors
(2013)
We study the existence and stability of multibreathers in Klein-Gordon chains with interactions that are not restricted to nearest neighbors. We provide a general framework where such long range effects can be taken into ...

Discrete embedded solitary waves and breathers in one-dimensional nonlinear lattices
(Elsevier, 2022-02)
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 continuous spectrum. Here, we extend this idea ...
