Many state-of-the-art technologies work at incredibly low temperatures. Superconducting microprocessors and quantum computers promise to revolutionize computation, but scientists need to keep them ...

The Kerr effect causes polarized light to rotate after interacting with magnetic domains in a material and enables the investigation of magnetized samples using Kerr microscopy. This method allows the ...

The researchers fabricated chip-based interferometers (pictured) to measure how light propagating through a magneto-optic material changed in response to a magnetic field. WASHINGTON — Researchers ...

Photon, an elementary particle that transmits electromagnetic interaction, is a kind of gauge boson. Photons are the carriers of electromagnetic radiation, and photons are considered as the medium of ...
