Interaction beween polarons and analogous effects in polarized Fermi gases
S. Giraud, R. Combescot
We consider an imbalanced mixture of two different ultracold Fermi gases, which are strongly interacting. Calling spin-down the minority component and spin-up the majority componen…

Comment on "Motion of an impurity particle in an ultracold quasi-one-dimensional gas of hard-core bosons [Phys. Rev. A 79, 033610 (2009)]"
S. Giraud, R. Combescot
Very recently Girardeau and Minguzzi [arXiv:0807.3366v2, Phys. Rev. A 79, 033610 (2009)] have studied an impurity in a one-dimensional gas of hard-core bosons. In particular they d…

Analytical theory of the dressed bound state in highly polarized Fermi gases
R. Combescot, S. Giraud, X. Leyronas
We present an analytical treatment of a single \down atom within a Fermi sea of \up atoms, when the interaction is strong enough to produce a bound state, dressed by the Fermi sea.…
