MIT News  May 2, 2024 The wavelength of light sets a typical length scale for most experiments to the order of 500 nanometers (nm) or greater. Researchers at MIT implemented a super-resolution technique that localizes and arranges atoms on a sub–50-nm scale, without any fundamental limit in resolution. They demonstrated this technique by creating a bilayer of dysprosium atoms and observing dipolar interactions between two physically separated layers through interlayer sympathetic cooling and coupled collective excitations. At 50-nm distance, dipolar interactions were 1000 times stronger than at 500 nm. According to the researchers for two atoms in optical tweezers, this […]
