Josephson tunnelling of a phase-imprinted Bose–Einstein condensate in a time-dependent double-well potential

This paper discusses the feasibility of experimental control of the flow direction of atomic Bose–Einstein condensates in a double-well potential using phase imprinting. The flow is induced by the application of a time-dependent potential gradient, providing a clear signature of macroscopic quantum tunnelling in atomic condensates. By studying both initial-state preparation and subsequent tunnelling dynamics, we find the parameters to optimize the phase-induced Josephson current. We find that the effect is largest for condensates of up to a few thousand atoms, and is only weakly dependent on trap geometry.

Control of tunneling oscillations between two coupled Bose-Einstein condensates by 2π pulse excitations

Noriaki Tsukada

Summary form only given. Dynamical control of the atomic tunneling between two Bose-Einstein condensates (BEC's) confined in a double-well potential is predicted to occur when laser pulses induce transition between one of the condensate state and the excited state which brings about phase shifts for the condensate wave function, leading to transition between macroscopic quantum self-trapping, which is a self-maintained population imbalance between two BEC's due to interatomic interaction, and large amplitude oscillations. We investigate this phenomenon for the case of a three-level system with two condensate states and an excited state.
