First-of-its-kind tube laser created for on-chip optical communications
Reversible solid-to-liquid phase transition offers new way to synthesize crystals
Nanoscale mirrored cavities amplify, connect quantum memories
The idea of computing systems based on controlling atomic spins just got a boost from new research performed at the Massachusetts Institute of Technology (MIT) and the U.S. Department of Energy's (DOE) Brookhaven ...
Entanglement on a chip: Breakthrough promises secure communications and faster computers
Unlike Bilbo's magic ring, which entangles human hearts, engineers have created a new micro-ring that entangles individual particles of light, an important first step in a whole host of new technologies.
Physicist suggests new experiments could make or break axion as dark matter theory
Engineering discovery brings invisibility closer to reality
Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered ...
Physicists find a new way to slow the speed of light
Scientists set quantum speed limit
University of California, Berkeley, scientists have proved a fundamental relationship between energy and time that sets a "quantum speed limit" on processes ranging from quantum computing and tunneling to ...
Exotic, gigantic molecules fit inside each other like Russian nesting dolls
University of Chicago scientists have experimentally observed for the first time a phenomenon in ultracold, three-atom molecules predicted by Russian theoretical physicist Vitaly Efimov in 1970.
New research re-creates planet formation, super-earths and giant planets in the laboratory
New laser-driven compression experiments reproduce the conditions deep inside exotic super-Earths and giant planet cores, and the conditions during the violent birth of Earth-like planets, documenting the ...
Peering into cosmic magnetic fields
The generation of cosmic magnetic fields has long intrigued astrophysicists. Since it was first described in 1959, a phenomenon known as Weibel filamentation instability—a plasma instability present in ...
New analysis shows a way to self-propel subatomic particles
Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.
New technology makes creating ultrashort infrared laser pulses easy and cheap
In a marathon, everyone starts at roughly the same place at roughly the same time. But the faster runners will gradually increase their lead, and in the end, the distribution of runners on the street will ...
New pathway to valleytronics
A potential avenue to quantum computing currently generating quite the buzz in the high-tech industry is "valleytronics," in which information is coded based on the wavelike motion of electrons moving through ...
