A crucial goal of spintronics research is to coherently manipulate electron spins at room temperature using electrical current. This is particularly valuable as it would enable the development of numerous devices, including ...
(PhysOrg.com) -- Of the many exotic and counterintuitive aspects of particle and quantum physics, exciton and polariton quasiparticles are among the most interesting. An exciton forms when a photon is absorbed by a semiconductor ...
Researchers from Brown University have shown experimentally how a unique form of magnetism arises in an odd class of materials called Mott insulators. The findings are a step toward a better understanding the quantum states ...
