Peierls-Nabarro barrier effect in nonlinear Floquet topological insulators

Mark J. Ablowitz, Justin T. Cole, Pipi Hu +1

The Peierls-Nabarro barrier is a discrete effect that frequently occurs in discrete nonlinear systems. A signature of the barrier is the slowing and eventual stopping of discrete s…
