A quarter-century after its discovery, physicists at the ATLAS Experiment at CERN are gaining new insight into the heaviest-known particle, the top quark. [41] Florida State University physicists believe they have an answer to unusual incidents of rare decay of a subatomic particle called a Kaon that were reported last year by scientists in the KOTO experiment at the Japan Proton Accelerator Research Complex. [40] In an unconventional new study, a team at Chalmers University of Technology in Sweden and the Max Planck Institute for the Science of Light set out to explore the interaction between a large atom and acoustic fields with wavelengths several orders of magnitude below the atomic dimensions. [39] The researchers acknowledge that aside from the "cool" factor, their achievement may not lead to any immediate practical applications, but suggest it might help with conducting studies of photons from the sun. [38] Fiber optic gyroscopes, which measure the rotation and orientation of airplanes and other moving objects, are inherently limited in their precision when using ordinary classical light. [37] Researchers have demonstrated the first quantum light-emitting diode (LED) that emits single photons and entangled photon pairs with a wavelength of around 1550 nm, which lies within the standard telecommunications window. [36] JILA scientists have invented a new imaging technique that produces rapid, precise measurements of quantum behavior in an atomic clock in the form of near-instant visual art. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy. [34] The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. [33] This scientific achievement toward more precise control and monitoring of light is highly interesting for miniaturizing optical devices for sensing and signal processing. [32]
