Topological routing in Chern insulators
Mark J. Ablowitz, Justin T. Cole, Sean D. Nixon
Chern insulator systems are realizable in numerous physical systems and can support robust nonreciprocal transmission of energy. A routing functionality constructed from two counte…

Quantitative measure of topological protection in Floquet systems through the spectral localizer
Stephan Wong, Alexander Cerjan, Justin T. Cole
The standard understanding of topological protection from band theory is that a system's topology cannot change without first closing the bulk band gap. However, in Floquet systems…

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…
