Abstract
The mass-imbalanced fermionic mixture is studied, where identical fermions interact resonantly with an impurity, a distinguishable atom. The shell structure is explored, and the physics of a dynamic light-impurity is shown to be different from that of the static heavy-impurity case. The energies in a harmonic trap at unitarity are calculated and extrapolated to the zero-range limit. In doing so, the scaling factor of the ground state, as well as of a few excited states, is calculated. In the systems, pure Efimov states exist for large enough mass ratio. However, no sign for a six-body Efimov state in the system is found in the mass ratio explored, .
