Observation of Unidirectional s-p Orbital Topological Edge States in Driven Photonic Lattices

Gayathry Rajeevan, Sebabrata Mukherjee

Time-periodic modulation of a static system is a powerful method for realizing robust unidirectional topological states. So far, all such realizations have been based on interactio…
