For a long time, physicists have tried to understand the relationship between a periodic pattern of conduction electrons called a charge density wave (CDW), and another quantum order, superconductivity, or zero electrical resistance, in the same material. Do they compete? Co-exist? Co-operate? Do they go their separate ways?
The international team of scientist of Peter the Great St. Petersburg Polytechnic University (SPbPU), Leibniz University Hannover (Leibniz Universität Hannover) and the Ioffe Institute found a way to improve nanocomposite material which opens new opportunities to use it in hydrogen economy and other industries. The study is dedicated to the composite material, a semiconductor based on titanium dioxide. Its applications are widely studied by the researchers all over the world.
Researchers at Purdue University and the University of Virginia have developed a new fabrication method that makes tiny, thin-film electronic circuits peelable from a surface. The technique not only eliminates several manufacturing steps and the associated costs, but also allows any object to sense its environment or be controlled through the application of a high-tech sticker.
Researchers have developed a microscopic "trampoline" that can absorb microwave energy and bounce it into laser light -- a crucial step for sending quantum signals over long distances.
Twenty-five researchers from seven research institutes have put their heads together to draw up rules for designing high-efficiency organic solar cells. The research is led by Feng Gao, associate professor at Linkoping University, Sweden.
'We now have a clear picture of how the hot atomic lattice and the cold magnetic spins of a ferrimagnetic insulator equilibrate with each other.' says Ilie Radu, scientist at the Max Born Institute Berlin. The international team of researchers discovered that energy transfer proceeds very quickly and leads to a novel state of matter in which the spins are hot but have not yet reduced their total magnetic moment.
A team led by Associate Professor Yang Hyunsoo from the National University of Singapore Faculty of Engineering has found a practical way to observe and examine the quantum effects of electrons in topological insulators and heavy metals. This could later pave the way for the development of advanced quantum computing components and devices.
New research from Binghamton University, State University at New York finds that mobile coupons can affect both short- and long-term sales goals, and that targeting customers with the right type of mobile coupon can boost revenue.
Australian scientists have achieved a new milestone in their approach to creating a quantum computer chip in silicon, demonstrating the ability to tune the control frequency of a qubit by engineering its atomic configuration. The work has been published in Science Advances.
Researchers at the US Army Research Laboratory and the Robotics Institute at Carnegie Mellon University developed a new technique to quickly teach robots novel traversal behaviors with minimal human oversight.
