Researchers from NIST and JQI have developed a new method to study the quantum Hall effect using light particles (photons) instead of electrons. The quantum Hall effect is a phenomenon where electrons flow along the edges of a conductor when a magnetic field is applied. This effect is currently used to create better electrical conductance standards.
The team built a silicon-based device with tiny ring-shaped structures that allow photons to flow along the edges, mimicking the quantum Hall effect. This approach has several advantages, including the ability to study the effect at room temperature and potentially leading to more efficient computer components that use light instead of electricity.
The device’s unique design allows photons to continue flowing even if some of the silicon rings are defective, making it more practical for manufacturing. This research could lead to new ways of studying quantum physics and developing advanced quantum technologies.
