University of Utah electrical and computer engineers have discovered a way to create an optics-less camera in which a regular pane of glass or any see-through window can become the lens.
Researchers recently discovered that the strength of the magnetic field required to elicit a particular quantum mechanical process 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.
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.
An international group led by Professor Beena Kalisky and Professor Aviad Frydman, from the Department of Physics and the Institute for Nanotechnology at Bar-Ilan University in Israel, has succeeded in imaging quantum fluctuations for the first time. In their experiment, published today in Nature Physics, not only were quantum fluctuations visualized, but new information about the sizes, times and distributions of quantum events was extracted.
A team led by researchers at Princeton University have made a finding that could help usher in new area of technology called 'valleytronics.' The study found that electrons in bismuth crystals prefer to collect in one valley rather than being distributed equally across valleys, setting up a type of electricity known as ferroelectricity.
An international team of scientists developed the world's first antilaser for nonlinear Bose-Einstein condensate of ultracold atoms. For the first time, scientists demonstrated that it is possible to absorb the selected signal completely, even though the nonlinear system makes it difficult to predict the waves behaviour. The results can be used to manipulate superfluid flows, create atomic lasers, and also study nonlinear optical systems. The study was published in Science Advances.
Nanosized magnetic particles called skyrmions are considered highly promising candidates for new data storage and information technologies. Now, physicists have revealed new behaviour involving the antiparticle equivalent of skyrmions in a ferromagnetic material. The researchers demonstrated their findings using advanced computer simulations that can accurately model magnetic properties of nanometre-thick materials. The results are published in Nature Electronics.
Pioneering engineers working with terahertz frequency technology have been researching how individual frequencies are selected when a laser is turned on, and how quickly the selection is made.
Researchers have demonstrated holonomic quantum gates under zero-magnetic field at room temperature, which will enable the realization of fast and fault-tolerant universal quantum computers.
New discovery published in Science explains what happens during the phase transition in Dirac materials, paving the way for engineering advanced electronics that perform significantly faster.
