New state of matter in one-dimensional quantum gas

phys.org
  • Scientists built a quantum version of the Archimedes screw which can stabilize gas atoms completely.
  • The screw also lets them observe scar states, an extremely rare repeating particle pattern in a quantum system - it’s only the second known observation ever.
  • They were trying to tweak a super Tonks-Girardeau gas, a highly excited one-dimensional quantum gas, which usually doesn’t hold up in experiments.
  • But here, researchers were able to make the gas remain stable no matter what, a result that was pretty much shocking to them.
  • The discovery doesn’t have an immediate application, but it’s a new addition to the science that will drive the creation and adoption of quantum technology.
