Universal Three-Body Parameter of Heavy-Heavy-Light systems with negative intraspecies scattering length
Abstract
we investigate the dependence of Three-body Parameter on the intraspecies interaction in heteronuclear atomic systems. Through calculating the | a-(1) | for ten mass imbalanced systems, we predict the universal dependence of | a-(1) | on the background scattering length aHH. We find that the | a-(1) | have a dramatically strong dependence on the background scattering length a<m:mstyle displaystyle="false" scriptlevel="2"> HH </m:mstyle> for the mass less-imbalanced systems, and for the strong mass imbalanced systems, the interspecies interaction plays less important role in determining the value of | a-(1) | . Specially, when the homonuclear atoms are in resonance, the a-(1) is nearly a constant expressed in terms of the van der Waals length r<m:mstyle displaystyle="false" scriptlevel="2"> vdW , HL </m:mstyle>: a-(1) = -(6 . 3 +/- 15 %) rvdW , HL .
