The experimental generation of increasingly intense light beams could help to unveil new physical regimes occurring in the presence of very strong electromagnetic fields. While some progress has been made towards this goal, ...
The wide availability of light-emitting devices (LEDs) for consumer use has led to a dramatic decrease in the cost of lighting our homes and other buildings. This is owing to the much higher efficiency of LEDs in converting ...
In physics, nonreciprocity occurs when a system's response varies depending on the direction in which waves or signals are propagating within it. This asymmetry arises from a break in so-called time-reversal symmetry, which ...
On 5 July 2022, protons began colliding again in the LHCb detector after a three-and-a-half-year break known as Long Shutdown 2 (LS2), marking the start of the third run of the Large Hadron Collider (LHC).
Thousands of particles of light can merge into a type of "super photon" under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate.
Dark matter is a hypothetical form of matter that is implied by gravitational effects that can't be explained by general relativity unless more matter is present in the universe than can be seen. It remains virtually as mysterious ...
The University of Manchester's National Graphene Institute has spearheaded an international team to engineer a novel approach for controlling thermal emission, detailed in a paper published in Science. This breakthrough offers ...
Purdue University engineers have developed a patent-pending method to synthesize high-quality, layered perovskite nanowires with large aspect ratios and tunable organic-inorganic chemical compositions.
Calcium oxide is a cheap, chalky chemical compound commonly used in the manufacturing of cement, plaster, paper, and steel. But the material may soon have a more high-tech application.
Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub.
