Phase separation and response of [Formula Presented] mixtures within a magnetic trap
We analyze the collective excitations of a mixture of fermionic and bosonic helium atoms in a random-phase approximation. The spectrum is shown to be highly fragmented, and its spread increases with the size of the Bose-Einstein condensate formed by [Formula Presented] atoms. In addition, the phase...

We analyze the collective excitations of a mixture of fermionic and bosonic helium atoms in a random-phase approximation. The spectrum is shown to be highly fragmented, and its spread increases with the size of the Bose-Einstein condensate formed by [Formula Presented] atoms.
