Collision of gravitationally bound Bose-Einstein condensates

The dynamics of head-on collisions of gravitationally bound Bose-Einstein condensates is studied. A fully consistent Schrodinger-Poisson system is solved numerically assuming axial symmetry about the axis of collision. Here, the investigation is focused on the regime where the head-on collisions of binary condensates exhibit solitonic nature of the condensates, inelastic collision properties, collision-induced collapse instability (in the case of attractive atomic interaction), and characteristic interference patterns that depend on the phase information (speed) of the colliding condensates.
