NIST physicists predict new form of soliton in ultracold gases 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 (NIST) and the University of Maryland, and their colleagues in India and the George Mason University, now believe that there may be a new...

Swooping through space are solitary waves, which in theory do not change form or lose energy as they go along. These waves, which exist on Earth in different media, have been detected and explained for the first time in space thanks to Cluster data. In theory, these solitary waves, called solitons, propagate endlessly maintaining their shape and form as well as velocity, which means that they do not lose energy with time. The phenomenon was first noticed in a water canal in England in 1834...
