Orbital angular momentum dynamics of Bose-Einstein condensates trapped in two stacked rings
Orbital angular momentum dynamics of Bose-Einstein condensates trapped in two stacked rings
We investigate the stability and dynamics of the orbital angular momentum modes of a repulsive Bose-Einstein condensate trapped in two tunnel-coupled rings in a stack configuration. Within mean-field theory, we derive a two-state model for the system in the case in which we populate both rings equally with a single …
