| Research Abstract |
We study molecular formations in the ultracold atomic-gas mixtures of bosonic and fermionic atoms with anisotropic dipolar interactions between the fermionic atoms and/or molecules, and clarifies the change of their phase structures for the molecular binding energies and interaction strengths. Especially the dipolar interactions act as attractive ones and make the mixtures unstable. We calculate the instability conditions in the case of the mixtures with molecular formations and make clear the effect for the phase structures of it. We also make some related researches on the bose-fermi mixtures.
