Everlasting Quantum Wave: Physicists Predict New Form of Soliton in Ultracold Gases

(PhysOrg.com) -- Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons. These everlasting waves are exotic enough, but theoreticians at the Joint Quantum Institute (JQI) , a collaboration of the National Institute of Standards and Technology and the University of Maryland, and their colleagues in India and the George Mason University, now believe that there may be a new kind of soliton that`s even more special. Expected to be found in certain types of ultracold gases, the new soliton would not be just a low-temperature atomic curiosity, it also may provide profound insights into other physical systems, including the early universe.
