Quantum Hall Insulator Enables One-Way Signal Flow in Resonators
Original: Quantum Hall Insulator Links Resonators For One-way Signal Flow
Researchers report that a quantum Hall insulator can be used to link resonators so that signals travel in only one direction, a property known as nonreciprocal transmission. The approach exploits the topological edge states characteristic of the quantum Hall effect, which could prove useful for routing signals in photonic or microwave circuits without backward reflections or interference.
Why now: Interest in topological physics and its practical applications to signal routing and robust communication devices
