Physicists have been working hard to improve the accuracy of atomic clocks, which are the most precise timing devices currently available. A promising way to achieve higher accuracy is to utilize spin squeezed states in clock atoms.Spin squeezed states are entangled quantum states in which particles work together to counteract their inherent quantum noise. These states provide incredible potential...
Summary:To filter out infrared light from the driving light source in the extreme ultraviolet lithography (EUVL) light source system, a rectangular grating structure needs to be fabricated on the surface of the collection mirror. However, the collection mirror grating usually undergoes deformation during the manufacturing process, resulting in a decrease in filtering efficiency. The process errors...
When researchers at the Max Planck Institute of Medicine conducted their first ultrafast X-ray crystallographic experiment on myoglobin in 2015, they were not aware that they had conducted the wrong experiment. By increasing the power of X-ray free electron lasers to ensure usable diffraction patterns, lead researcher Ilme Schlichting said that they "suddenly entered the wrong [excited] state with...
Us researchers report 8.1 μm wavelength quantum cascade laser (QCL) grown on silicon (Si) by MOCVD [S. Xu et al., Applications. Physics Letters, v123, p031110, 2023]. "There are no previous reports of QCL growth on silicon substrates by metal-organic chemical vapor deposition (MOCVD)," commented the team from the University of Wisconsin-Madison, the University of Illinois at Urbana-Champaign an...
Due to the increasing threat of space debris in low Earth orbit around the Earth, space agencies around the world are becoming increasingly concerned about this. According to a new study funded by the National Aeronautics and Space Administration (NASA), it may be possible to send space debris that may be at risk of colliding with orbiting spacecraft to safer orbits through a laser network deploye...
