Observation of Topological Band Gap Solitons
Sebabrata Mukherjee, Mikael C. Rechtsman
Abstract
We present the first experimental observation of solitons in the bulk of a photonic Floquet topological insulator. We probe a family of these nonlinear states residing on the topological band gap and performing cyclotron-like orbits.
