    • A circular scan was produced by modulating the radio frequency of the two AOS's with a π/2 phase shift between the modulating signals. The radius of rotation was determined by the modulation amplitude.

    • The temperatures of the atoms at this point were reduced from 17 μK (53 μK) to 10 μK (16 μK) in the axial (radial) direction.

    • With a very small number of atoms we were able to cool the atoms back to their initial temperature even in a compressed trap.

    • To verify that the nonexponential loss is not caused by the compression process, we repeated it with a very small number of atoms, and found a purely exponential decay after compression.

    • note
    • Temperature measurements at lower densities and results of the MC simulations did not reveal temperature equalization, which verifies that equalization is caused by elastic collisions and not by the unharmonicity of the potential.
