“…For a 7 Li-6 Li collision, on the other hand, the scattering length is ≈ 38 a.u. [14]. From this we deduce thatñ F = 1 corresponds to the density n F = 9.3 · 10 23 m −3 , which is several orders of magnitude higher than the densities which can presently be realized experimentally.…”

We calculate the phase diagram for dilute mixtures of bosons and fermions at zero temperature. The linear stability conditions are derived and related to the effective boson-induced interaction between the fermions. We show that in equilibrium there are three possibilities: a) a single uniform phase, b) a purely fermionic phase coexisting with a purely bosonic one and c) a purely fermionic phase coexisting with a mixed phase.

“…For smaller r we use the model singlet and triplet potentials, which have also been used in Refs. [15,16]. These short-and long-range potentials are smoothly connected at r =18a 0 , with a 0 the Bohr radius.…”

We perform an analysis of recent experimental measurements and improve the lithium interaction potentials. For 6 Li a consistent description can be given. We discuss theoretical uncertainties for the position of the wide 6 Li Feshbach resonance, and we present an analytic scattering model for this resonance, based on the inclusion of a field-dependent virtual open-channel state. We predict new Feshbach resonances for the 6 Li-7 Li system, and their importance for different types of crossover superfluidity models is discussed.

“…In other situations a bg can be large and negative, indicating that the interaction potential has a virtual state near threshold. Examples here are 85 Rb with a bg = −443a 0 [14], and 6 Li where a bg Ϸ −2000a 0 [29,30]. In these cases, the nonresonant description of the background scattering process is not correct.…”
