Collisions of ultracold ground-state NaRb molecules

In this talk, I will report our recent work on the production and investigation of an ultracold sample of absolute ground-state $^{\mathrm{23}}$Na$^{\mathrm{87}}$Rb molecules via Raman transfer of weakly bound molecules formed by magnetoassociation. A series of investigations, including the inelastic collisions with different chemical reactivity and with and without the induced dipole-dipole interaction, will be discussed.
