Topological edge transport in a Lieb-like photonic lattice

Not Accessible

Your library or personal account may give you access

Abstract

We report on topologically protected edge states in a four-band Lieb-like photonic lattice of evanescently coupled helical waveguides. Our results demonstrate adjustable group velocities depending on the driving potential and the selected edge termination.
