Quantum Degenerate Gases of Strontium

POSTER

Abstract

We have produced quantum degenerate gases of three of the four stable isotopes of strontium. Using two-stage laser trapping and cooling followed by direct evaporative cooling in a far-off- resonance optical dipole trap (ODT), a stable Bose-Einstein Condensate (BEC) of $^{84}$Sr is formed. Via dual species trapping and sympathetic cooling in an ODT, an attractive BEC of $^{88}$Sr is created, as well as a degenerate Fermi gas of $^{87}$Sr. Differences in the evaporation scheme used to reach degeneracy for each isotope will be presented as well as the varied dynamics of the gases.
