Explosion-implosion duality in the Bose-Einstein condensation

Abstract

We show an explosion-implosion duality in the one and two dimensional Bose-Einstein condensation with or without a particular time-dependent harmonic trap. The result is independent of the strength and the attractive or the repulsive nature of the self-interaction of the condensate. This implies that the implosion in a particular atomic species has a dual description in terms of the explosion in the same or another atomic species and the vice versa. The result is applicable without any modifications to nonrelativistic theories that are invariant under the SL(2,R) reparameterization of the time-coordinate.
