Observation of antichiral edge states in a circuit lattice

A modified Haldane lattice exhibits the intriguing phenomenon of antichiral edge states that propagate in the same direction on opposite edges and co-exist with bulk states. Using an electric circuit, researchers have successfully ...

Steering light to places it isn't supposed to go

Light that is sent into a photonic crystal can't go deeper than the so-called Bragg length. Deeper inside the crystal, light of a certain color range can simply not exist. Still, researchers of the University of Twente, the ...
