Many-body dynamics of a Bose-Einstein condensate collapsing by quantum tunneling
Many-body dynamics of a Bose-Einstein condensate collapsing by quantum tunneling
The dynamics of a Bose-Einstein condensate of atoms having attractive interactions is studied using quantum many-body simulations. The collapse of the condensate by quantum tunneling is numerically demonstrated, and the tunneling rate is calculated. The correlation properties of the quantum many-body state are investigated.
