(PhysOrg.com) -- Matter in the subatomic realm is, well, a different matter. In the case of strongly correlated phases of matter, one of the most surprising findings has to do with a phenomenon known as the Hall response – an important theoretical and experimental tool for describing emergent charge carriers in strongly correlated systems, examples of which include high temperature superconductors and the quantum Hall effect.
Researchers have used an electric field to reverse the magnetization direction in a multiferroic spintronic device at room temperature, a demonstration that points a new way towards spintronics and smaller, faster and cheaper ways o... Read Post
(PhysOrg.com) -- Subatomic events can be remarkably counterintuitive. Such is the case in theoretical physics when, under certain specific conditions, atoms exposed to intense infrared laser pulses remain stable rather than undergoi... Read Post
Earth's north magnetic pole is shifting and weakening. Ancient lava flows are guiding a better understanding of what generates and controls the Earth's magnetic field -- and what may drive it to occasionally reverse direction. Curre... Read Post
