An international research team led by physicists at the University of California, Riverside, has revealed a new quantum process in valleytronics that can speed up the development of this fairly new technology.
Valleytronics, a portmanteau of "valley" and "electronics," uses...
Humans have been studying electric charge for thousands of years, and the results have shaped modern civilization. Our daily lives depend on electric lighting, smartphones, cars, and computers, in ways that the first individuals to take note of a...
Researchers say a new discovery on a U.S. Army project for optoelectronic devices could help make optical fiber communications more energy efficient.
The University of Pennsylvania, Peking University and Massachusetts Institute of Technology worked on a project funded, in part...
Physicists use an interferometer to test whether standard quantum mechanics is correct, or whether a more complex version is required. They used the interferometer to send photons around a loop in opposite directions. In this way, photons travelling in...
Adding nanoscale particles of aluminum oxide increases the depth of the melting zone (MZ) in nickel and decreases the size of the heat-affected zone (HAZ). The bottom right image shows how even at higher temperatures the heat affected zone...
For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials that were theorized to exist only in four-dimensional space. An international team of researchers from Penn State, ETH...
When stars explode as supernovas, they produce shock waves in the plasma surrounding them. So powerful are these shock waves, they can act as particle accelerators that blast streams of particles, called cosmic rays, out into the universe at...
Among the chief complaints for smartphone, laptop and other battery-operated electronics users is that the battery life is too short and—in some cases—that the devices generate heat. Now, a group of physicists led by Deepak K. Singh, associate professor...
“…f a fluorescence microscope’s resolution is set at 2 micrometers, our technique can have 300 nanometer resolution — about a sixfold improvement over regular microscopes,” says MIT graduate student Frederick Sangyeon Cho. “The idea is very simple but very...
This is an example of the Hofstadter butterfly phenomenon.

A team of Graphene Flagship researchers led by the University of Manchester reported in the journal Science showing the first new type of quantum oscillation to be...
Electrons flowing across the boundary between two materials are the foundation of many key technologies, from flash memories to batteries and solar cells. Now researchers have directly observed and clocked these tiny cross-border movements for the first time, watching...
