Coupled-mode theory for Bose–Einstein condensates with time dependent atomic scattering length
We study nonlinear tunnelling and localization phenomena in Bose–Einstein condensate in a double-well potential, using a coupled-mode theory. We consider the effects induced by the damping and an atomic scattering length oscillating in time in a double-well potential. The existence of synchronous so...

| description | We study nonlinear tunnelling and localization phenomena in Bose–Einstein condensate in a double-well potential, using a coupled-mode theory. We consider the effects induced by the damping and an atomic scattering length oscillating in time in a double-well potential. The existence of synchronous solutions in a running phase mode and resonances in macroscopic quantum tunnelling for such system are investigated. The switching between macroscopic quantum tunnelling and quantum self-trapped regimes induced by periodic modulations of the scattering length is also studied. |
