Physics Letters A, 384 (26), 126664-.0375-9601https://hdl.handle.net/11441/100879We 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 inside the band of linear modes. We identify a number of discrete breathers both existing in the bulk and also (predominantly) ones arising at the domain boundaries, localized either along the arm-chair or along the zig-zag edges. The types of edge-localized breathers observed and computed emerge in distinct frequency bands near the Dirac-point frequency of the dispersion surface while driving the lattice subharmonically (in a spatially homogeneous manner). These observations/computations can represent a starting point towards the exploration of the interplay of nonlinearity and topology in an experimentally tractable system such as the honeycomb electrical lattice.application/pdf7 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Intrinsic localized modesDiscrete breathersEdge breathersNonlinear edge modes in a honeycomb electrical lattice near the Dirac pointsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1016/j.physleta.2020.126664
