    Researchers who study and manipulate the behavior of materials at the atomic level have discovered a way to make a thin material that enhances the flow of microwave energy. The advance, which could improve telecommunications, sheds new light on structural traits, generally viewed as static and a hindrance, that, when made to be dynamic, are actually key to the material's special ability. [...]

    Researchers recently discovered that the strength of the magnetic field required to elicit a particular quantum mechanical process, such as photoluminescence and the ability to control spin states with electromagnetic (EM) fields, corresponds to the temperature of the material. Based on this finding, scientists can determine a sample's temperature to a resolution of one cubic micron by measuring the field strength at which this effect occurs. Temperature sensing is integral in most industrial, electronic and chemical processes, so greater spatial resolution could benefit commercial and scientific pursuits. The team reports their findings in AIP Advances. [...]

    Quantum technology is a growing field of physics and engineering which utilizes properties of quantum mechanics as a basis for advanced practical applications such as quantum computing, sensors, information, communication and medicine. This promises to lead to a new era of technology unlike anything we've known. Computers will be much more powerful, medical treatment will be non-invasive and far safer than today, and even teleportation can be envisioned. A phenomenon that stands at the core of this development is the Quantum phase transition. [...]

    Last year, physicists at MIT, the University of Vienna, and elsewhere provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in space and time, can be inextricably linked, in a way that defies the rules of classical physics. [...]

    The transition from light bulbs to LEDs has drastically cut the amount of electricity we use for lighting. Most of the electricity consumed by incandescent bulbs was, after all, dissipated as heat. We may now be on the verge of a comparable breakthrough in electronic computer components. Up to now, these have been run on electricity, generating unwanted heat. If spin current were employed instead, computers and similar devices could be operated in a much more energy-efficient manner. Dr. Olena Gomonay from Johannes Gutenberg University Mainz (JGU) in Germany and her team together with Professor Eiji Saitoh from the Advanced Institute for Materials Research (AIMR) at Tohoku University in Japan and his work group have now discovered an effect that could make such a transition to spin current a reality. This effect significantly simplifies the design of fundamental spintronic components. [...]
