There has been an intense search in recent years for long-lived spin-polarized carriers for spintronic and quantum-computing devices. Here we report that spin polarized quasi-particles in superconduct...
Heat can be conducted across a nanometre-sized vacuum gap – something that was deemed impossible until now. So say researchers at the Air Force Research Laboratory in Ohio who have found that the heat...
