Simon Fraser University researchers have designed a remarkably fast engine that taps into a new kind of fuel -- information.
The development of this engine, which converts the random jiggling of a microscopic particle into stored energy, is outlined in...
Unlike the oscillations of sound waves, the oscillations of light are so fast that extremely complex equipment is needed to observe them directly. However, it is possible to measure the frequencies of these oscillations indirectly with frequency combs. These...
The use of multimode optical fibers to boost the information capacity of the Internet is severely hampered by distortions that occur during the transmission of images because of a phenomenon called modal crosstalk.
However, University of Rochester researchers at the...
They may be tiny weapons, but Brigham Young University's holography research group has figured out how to create lightsabers -- green for Yoda and red for Darth Vader, naturally -- with actual luminous beams rising from them.
Inspired by the...
Scientists from Texas A&M have developed an extension to an ordinary cellphone that turns it into an instrument capable of detecting chemicals, drugs, biological molecules, and pathogens. The advance is reported in Reviews of Scientific Instruments, by AIP Publishing.
Modern...
The uncertainty principle, first introduced by Werner Heisenberg in the late 1920's, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all electrical product can also behave like waves. As a...
In material physics understanding how systems interact across the interfaces separating them is of central interest. But can physical models clarify similar concepts in living systems, such as cells? Physicists at the University of Geneva (UNIGE), in collaboration with...
Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology.
The new technology uses the first known holographic optical engineering device to control trapped ion qubits. This technology promises to help create more precise...
As the digital revolution has now become mainstream, quantum computing and quantum communication are rising in the consciousness of the field. The enhanced measurement technologies enabled by quantum phenomena, and the possibility of scientific progress using new methods, are...
When two people want different things, frustration is inevitable. But these non-reciprocal interactions can also occur not just between people, but in the natural world.
In a paper published April 14 in the journal Nature, a team of University of Chicago...
"Image" is everything in the $20 billion market for AR/VR glasses. Consumers are looking for glasses that are compact and easy to wear, delivering high-quality imagery with socially acceptable optics that don't look like "bug eyes."
University of Rochester researchers...
