Nanopillared lenses let scientists trap individual atoms with light

“Optical tweezers” – systems that focus light to trap and manipulate individual atoms – could pave the way for powerful quantum devices, but they can be a little cumbersome. Researchers have now developed a simplified, smaller design for optical tweeze… Continue reading Nanopillared lenses let scientists trap individual atoms with light

Physicists measure gravitational time warp to within one millimeter

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at different speeds across just one millimeter, the smallest d… Continue reading Physicists measure gravitational time warp to within one millimeter
