主　　题：Bose-Einstein condensate(BEC) p-wave s-wave miscibility-immiscibility transition 

摘      要：Combining two Bose-Einstein condensates(BECs)may result in a miscible or immiscible *** this study,we investigate the miscibility-immiscibility transition of binary BEC mixture trapped in an isotropic harmonic potential,with both inter-species s-wave and p-wave scattering interaction *** mean-field Gross-Pitaevskii equations with p-wave interaction term are numerically solved to obtain the ground-state phase *** to the pwave interaction competing with isotropic s-wave interaction,the spatial density profile of binary BEC mixtures transforming from immiscible phase to miscible phase is *** p-wave interaction caused miscibility can be observed in current experiments of Bose-Bose mixture tuned near a p-wave Feshbach resonance.
