Tuning skyrmion helicity for racetrack memory and quantum computing applications
Three distinct topological degrees of freedom are used to define all topological spin textures based on out-of-plane and in-plane spin configurations: the topological charge, representing the number of times the magnetization vector m wraps around th.....»»
The first search for soft unclustered energy patterns in proton–proton collisions at 13TeV
A key objective of many physics studies is to experimentally observe exotic phenomena beyond the Standard Model (SM) that are predicted by theoretical models. These include hidden valley models, which predict the existence of a dark sector in which p.....»»
Deformable mirror technology takes laser welding and 3D printing to new heights

3D models help researchers understand the climate impact of eddies
Mesoscale eddies are ocean vortices less than 100 kilometers in diameter that are responsible for the localized "weather" of the oceans. Because of the large amount of mass and energy movement associated with these currents, mesoscale eddies play an.....»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
Citizen scientist data help uncover the mysteries of a blue low-latitude aurora
Colorful auroras appeared around Japan's Honshu and Hokkaido islands on May 11, 2024, sparked by an intense magnetic storm. Usually, auroras observed at low latitudes appear red due to the emission of oxygen atoms. But on this day, a salmon pink auro.....»»
