Death of soliton trains in attractive Bose-Einstein condensates
Alexej I. Streltsov, Ofir. E. Alon, Lorenz S. Cederbaum
Experiments on ultra-cold attractive Bose-Einstein Condensates (BECs) have demonstrated that at low dimensions atomic clouds can form localized objects, propagating for long times…
Mechanism of Tunneling in Interacting Open Ultracold Few-Boson Systems
Axel U. J. Lode, Alexej I. Streltsov, Ofir E. Alon +1
We investigate the mechanism in the tunneling dynamics of open ultracold few-boson systems by numerically solving the time-dependent few-boson Schrödinger equation exactly. By star…
Fragmented Many-Body states of definite angular momentum and stability of attractive 3D Condensates
Marios C. Tsatsos, Alexej I. Streltsov, Ofir E. Alon +1
A three dimensional attractive Bose-Einstein Condensate (BEC) is expected to collapse, when the number of the particles in the ground state or the interaction strength ex…
