Special Session 110: Nonlinear Schrodinger equations and its applications
Contents
We numerically analyze the relation between coherent tunneling and creation and annihilation of quantized vortex rings in a dilute Bose-Einstein condensate confined in a double-well trap. We show that while plasma oscillations are related to the dynamics of external vortex rings, in the self-trapping regime the vortices exist at the barrier and act as precursors of the flow inversion. We show that vortices are a crucial ingredient to completely understand the tunneling dynamics in a bosonic Josephon junction.
