1. Bosenova

   A bosenova or bose supernova is a very small, supernova-like explosion, which can be induced in a Bose–Einstein condensate (BEC) by changing the external magnetic field, so that the "self-scattering" interaction transitions from repulsive to attractive due to the Feshbach resonance, causing the BEC to "collapse and bounce" or "rebound."Although the total energy of the explosion is very small, the "collapse and bounce" scenario qualitatively resembles a condensed matter version of a core-collapse supernova, hence the term bosenova. The nomenclature is not a play of words on the Brazilian music style bossa nova, but a play of words with bose-einstein and supernova.

1. Bosenova

   A bosenova or bose supernova is a very small, supernova-like explosion, which can be induced in a Bose–Einstein condensate by changing the magnetic field in which the BEC is located, so that the BEC quantum wavefunction's self-interaction becomes attractive. In the particular experiment when a bosenova was first detected, this procedure caused the BEC to implode and shrink beyond detection, and then suddenly explode. In this explosion, about half of the atoms in the condensate seem to have disappeared from the experiment altogether, remaining undetected either in the cold particle remnants or in the expanding gas cloud produced. "The 'missing' atoms are almost certainly still around in some form, but just not in a form that we can detect them in our current experiment," Carl Wieman told SPACE.com. "The two likely possibilities are that they have formed into molecules of two rubidium atoms stuck together, or they have gotten enough energy from somewhere to fly away fast enough that they are out of our observation region before we look for them." Under current quantum theory, this characteristic of Bose–Einstein condensate remains unexplained, because the energy state of an atom near absolute zero appears to be insufficient to cause the observed implosion. However, subsequent mean-field theories have been proposed to explain the phenomenon.
