Since the early days of ultracold atomic physics, the phenomena of matter wave collapse, i.e. unrestricted contraction of the Bose-Einstein condensate (BEC) with attractive interatomic interactions, has been studied both experimentally  and theoretically . In particular, it has been shown that a dynamically stable BEC can exist both in 3D and 2D (strongly anisotropic, pancake) harmonic traps, as long as the number of particles in the condensate is below a certain critical value....[Show more]
