Normal-Superfluid Interface for Polarized Fermion Gases
Bert Van Schaeybroeck, Achilleas Lazarides
Recent experiments on imbalanced fermion gases have proved the existence of a sharp interface between a superfluid and a normal phase. We show that, at the lowest experimental temp…
Collective Excitations of Harmonically Trapped Ideal Gases
Bert Van Schaeybroeck, Achilleas Lazarides
We theoretically study the collective excitations of an ideal gas confined in an isotropic harmonic trap. We give an exact solution to the Boltzmann-Vlasov equation; as expected fo…
Trapped Phase-Segregated Bose-Fermi Mixtures and their Collective Excitations
Bert Van Schaeybroeck, Achilleas Lazarides
Recent progress in the field of ultracold gases has allowed the creation of phase-segregated Bose-Fermi systems. We present a theoretical study of their collective excitations at z…
