Controlling quantum interactions in a single material

Science Daily  February 5, 2018
Using computational simulations, an international team of researchers (USA – Northwestern University, Austria, Germany, China) discovered coexisting quantum-mechanical interactions in the compound silver-bismuth-oxide. Bismuth enables the spin of the electron to interact with its own motion and does not exhibit inversion symmetry. By applying an electric field to the material, researchers were able to control whether the electron spins were coupled in pairs or separated as well as whether the system is electrically conductive or not. The findings could enable ultrafast, low-power electronics and quantum computers that operate faster than current models… read more.  Open Access TECHNICAL ARTICLE
