In 1995, dilute alkali atoms were cooled to form a Bose-Einstein condensate. These systems are intermediate between an ideal Bose gas and dense liquid helium. Their dilute character makes them accessible to an accurate theoretical treatment. Current problems of interest include the shape and stability of single vortices, the physics of rapidly rotating condensates with many vortices, and the behavior and stability of one-dimensional arrays in an optical lattice.
