We report two novel techniques for cooling and rotating Bose-Einsteincondensates in a dilute rubidium vapour that highlight the control andversatility afforded over cold atom systems by time-averaged adiabaticpotentials (TAAPs). The intrinsic loss channel of the TAAP has beensuccessfully employed to evaporatively cool a sample of trapped atoms toquantum degeneracy. The speed and efficiency of this process compares well withthat of conventional forced rf-evaporation. In an independent experiment, weimparted angular momentum to a cloud of atoms forming a Bose-Einsteincondensate by introducing a rotating elliptical deformation to the TAAPgeometry. Triangular lattices of up to 60 vortices were created. All findingsreported herein result from straightforward adjustments of the magnetic fieldsthat give rise to the TAAP.
