Data-driven approximations of topological insulator systems
Justin T. Cole, Michael J. Nameika
A data-driven approach to calculating tight-binding models for discrete coupled-mode systems is presented. Specifically, spectral and topological data is used to build an appropria…

The Haldane Model in a Magneto-optical Honeycomb Lattice
M. J. Ablowitz, J. T. Cole
A two-dimensional honeycomb lattice composed of gyrotropic rods is studied. Beginning with Maxwell's equations, a perturbed Wannier method is introduced which yields a tight-bindin…

Switching via Wave Interaction in Topological Photonic Lattices
Mark J. Ablowitz, Justin T. Cole, S. D. Nixon
A honeycomb Floquet lattice with helically rotating waveguides and an interface separating two counter-propagating subdomains is analyzed. Two topologically protected localized wav…
