Description
Using Optimal Control Theory (OCT), we design fast ramps for the controlled transport of Bose-Einstein
condensates with atom chips’ magnetic traps. These ramps are engineered in the context of precision
atom interferometry experiments and support transport over large distances, typically of the order of
1 mm, i.e. about 1,000 times the size of the atomic clouds, yet with durations not exceeding 200 ms. We
show that with such transport durations of the order of the trap period, one can recover the ground state
of the final trap at the end of the transport. The performance of the OCT procedure is compared to that
of Shortcut-To-Adiabaticity (STA) protocols and the respective advantages / disadvantages of the OCT
treatment over the STA one are discussed.
