PTB researchers want to construct the "atomic clock of the future" much more simply and more compactly than the previous elaborate laboratory set-ups.
Transitions are exciting. And at temperatures close to absolute zero, studying the transition from one quantum phase to another tantalizes physicists looking for a deeper understanding of the fundamental laws of the universe.
Ohio State University researchers have developed a new strategy to overcome one of the major obstacles to a grand challenge in physics.
Physicists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have proposed a recipe for turning ultracold â€œbosonâ€ atomsâ€”the ingredients of Bose-Einstein condensatesâ€”into a â€œsupersolid,â€ an exotic state of matter that behaves simultaneously as a solid and a friction-free superfluid.
Physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms.
Ultracold atoms moving through a carefully designed arrangement of laser beams will jiggle slightly as they go, two NIST scientists have predicted.* If observed, this never-before-seen â€œjitterbugâ€ motion would shed light on a little-known oddity of quantum mechanics arising from Paul Diracâ€™s 80-year-old theory of the electron.
