Researchers have demonstrated the world's first metasurface laser that produces "super-chiral light": light with ultra-high angular momentum. The light from this laser can be used as a type of "optical spanner" to or for encoding information in optical communications.
"Because light can...
Advanced, fault-tolerant quantum computers may be closer to reach than scientists have projected, according to recent advances reported by Johns Hopkins researchers in a new study recently published in Physical Review Letters.
The researchers built on their previous study about the...
The fundamental laws of physics are based on symmetries that determine the interactions between charged particles, among other things. Using ultracold atoms, researchers at Heidelberg University have experimentally constructed the symmetries of quantum electrodynamics. They hope to gain new...
A Monash-led study develops a new approach to directly observe correlated, many-body states in an exciton-polariton system that go beyond classical theories.
The study expands the use of quantum impurity theory, currently of significant interest to the cold-atom physics community,...
Atoms and molecules behave very differently at extreme temperatures and pressures. Although such extreme matter doesn't exist naturally on the earth, it exists in abundance in the universe, especially in the deep interiors of planets and stars. Understanding how...
A team of University of Alberta engineers is refining a new imaging technique that could reduce the number of repeat surgeries patients undergo to remove cancerous tumors.
The team, led by Roger Zemp, is using ultraviolet photoacoustic remote sensing microscopy...
The destructive force of a tornado occurs due to the extremely high rotational speeds in its center, which is called a vortex. Surprisingly, similar effects are predicted for light that travels along an atomically smooth gold surface, which can...
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...
Scientists at Ames Laboratory, Brookhaven National Laboratory, and the University of Alabama Birmingham have discovered a light-induced switching mechanism in a Dirac semimetal. The mechanism establishes a new way to control the topological material, driven by back-and-forth motion of...
For years, researchers have searched for the working principles of self-assembly that can build a cell (a complex biological organism) as well as a crystal (a far simpler inorganic material) in the same way.
Now, a team of scientists in...
Experimental condensed matter physicists in the Department of Physics at the University of Oklahoma have developed an approach to circumvent a major loss process that currently limits the efficiency of commercial solar cells.
Solar cells convert the sun's energy into electricity and...
