dc.description.abstractWe demonstrate control of the collapse and expansion of an Sr88 Bose-Einstein condensate using an optical Feshbach resonance near the S01−P13 intercombination transition at 689 nm. Significant changes in dynamics are caused by modifications of scattering length by up to ±10abg, where the background scattering length of Sr88 is abg=−2a0 (1a0=0.053  nm). Changes in scattering length are monitored through changes in the size of the condensate after a time-of-flight measurement. Because the background scattering length is close to zero, blue detuning of the optical Feshbach resonance laser with respect to a photoassociative resonance leads to increased interaction energy and a faster condensate expansion, whereas red detuning triggers a collapse of the condensate. The results are modeled with the time-dependent nonlinear Gross-Pitaevskii equation.en_US
