Fig. 1. (a) Diagram of the double-well trap created by the atom chip. The red lines represent current-carrying wires while the arrows indicate the direction of current. B0 is the bias magnetic field in y direction. Curve U shows the potential distribution along the x axis; (b) potential distribution of the double-well trap model along the x axis. The initial double-well trap is shown as the solid line. With the uplift of the bottom of the left sub-well (dashed line),the atoms are gradually transported f
Fig. 2. (a) The evolution of the atom number in the right sub-well with time, as the initial atom number in the left sub-well is different. The gain of atom number can be obtained by fitting the curve at the beginning of transport (curve segment in the shadow, namely 10.9 ms
Fig. 3. (a) The evolution of the total atom number (solid lines) and the atom number in the right sub-well (dashed lines) with time, as the initial temperature of the atomic cloud in the left sub-well is different. The gain of atom number can be obtained by fitting the curve segment in the shadow (namely 0.07×105
Fig. 4. (a) The evolution of the atom number in the right sub-well with time, as the time of shallowing for the left sub-well is different. The gain of atom number can be obtained by fitting the curve segment in the shadow (namely 0.07×105
