Configurable topological beam splitting via antichiral gyromagnetic photonic crystal
Topological insulators, whose bulky states are prohibited while surface/edge states are conductive and topologically protected. Recent advances in topologically protected edge states have drawn growing attention in the optics and photonics community......»»
Generalized splitting-ring number theoretic transform
Number theoretic transform (NTT) is widely recognized as the most efficient method for computing polynomial multiplication with high dimension and integral coefficients, due to its quasilinear complexity......»»
Superconductivity study confirms existence of edge supercurrents
Topological materials are materials that have unusual properties that arise because their wavefunction—the physical law guiding the electrons—is knotted or twisted. Where the topological material meets the surrounding space, the wavefunction must.....»»
Sonos Beam soundbar for $100 cheaper with this early Labor Day deal

Quality control: Neatly arranging crystal growth to make fine thin films
Table salt and refined sugar look white to our eyes, but that is only because their individual colorless crystals scatter visible light. This feature of crystals is not always desirable when it comes to materials for optical and electrical devices, h.....»»
Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid
The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions......»»

Green hydrogen: "Artificial leaf" becomes better under pressure
Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so-called photoelectrochemical cells (PEC cells). A research team at HZB has now sh.....»»
Ammonia-free gallium nitride semiconductor production found to improve crystal quality, reduce environmental impact
Gallium nitride (GaN) semiconductors can now be grown without ammonia, a toxic chemical that needs a sophisticated detoxifying system before it can be released into the atmosphere. The new technique is not only more environmentally friendly but also.....»»
Researchers trap atoms, force them to serve as photonic transistors
Researchers at Purdue University have trapped alkali atoms (cesium) on an integrated photonic circuit, which behaves like a transistor for photons (the smallest energy unit of light) similar to electronic transistors. These trapped atoms demonstrate.....»»
NASA, JAXA bounce laser beam between moon"s surface and lunar orbit
NASA's LRO (Lunar Reconnaissance Orbiter) has twice transmitted a laser pulse to a cookie-sized retroreflector aboard JAXA's (Japan Aerospace Exploration Agency) SLIM lander on the moon and received a return signal......»»
