Bifurcations of edge states—topologically protected and non-protected—in continuous 2D honeycomb structures
Bifurcations of edge states—topologically protected and non-protected—in continuous 2D honeycomb structures
Edge states are time-harmonic solutions to energy-conserving wave equations, which are propagating parallel to a line-defect or 'edge' and are localized transverse to it. This paper summarizes and extends the authors' work on the bifurcation of topologically protected edge states in continuous two-dimensional (2D) honeycomb structures. We consider a family …
