We discuss the behavior of weakly bound bosonic dimers formed in a two-component cold Fermi gas at a large positive scattering length a for the interspecies interaction. We find the exact solution for the dimer-dimer elastic scattering and obtain a strong decrease of their collisional relaxation and decay with increasing a. The large ratio of the elastic to inelastic rate is promising for achieving Bose-Einstein condensation of the dimers and cooling the condensed gas to very low temperatures. 
Collective excitations of strongly interacting Fermi gases of atoms in a harmonic trap
The zero-temperature properties of a dilute two-component Fermi gas in the BCS to Bose-Einstein Condensation crossover are investigated. On the basis of a generalization of the Hylleraas-Undheim
Scattering of universal fermionic clusters in the resonating group method
Mixtures of polarised fermions of two different masses can form weakly-bound clusters, such as dimers and trimers, that are universally described by the scattering length between the heavy and light
Superfluid regimes in degenerate Fermi gases
We give a brief overview of recent studies of quantum degenerate regimes in ultracold Fermi gases. The attention is focused on the regime of Bose-Einstein condensation of weakly bound molecules of
LETTER TO THE EDITOR: Hydrodynamic modes in a trapped strongly interacting Fermi gas of atoms
The zero-temperature properties of a dilute two-component Fermi gas in the Bardeen–Cooper–Schrieffer phase–Bose–Einstein condensate crossover are investigated. On the basis of a generalization of the
Atom-dimer and dimer-dimer scattering in fermionic mixtures near a narrow Feshbach resonance
Abstract We develop a diagrammatic approach for solving few-body problems in heteronuclear fermionic mixtures near a narrow interspecies Feshbach resonance. We calculate s-, p-, and d-wave
Bragg spectroscopy of a strongly interacting Fermi gas.
TLDR
These spectra probe the dynamic and static structure factors of the gas and provide a direct link to two-body correlations and are characterized and measured their density dependence across the broad Feshbach resonance at 834 G.
Realization of a strongly interacting Bose-Fermi mixture from a two-component Fermi gas.
TLDR
This study realizes a gedanken experiment of bosons immersed in a Fermi sea of one of their constituents, revealing the composite nature of the bosons.
Diatomic molecules in ultracold Fermi gases - novel composite bosons.
We give a brief overview of recent studies of weakly bound homonuclear molecules in ultracold two-component Fermi gases. It is emphasized that they represent novel composite bosons, which exhibit
The role of multiparticle correlations and Cooper pairing in the formation of molecules in an ultracold gas of Fermi atoms with a negative scattering length
The influence of multiparticle correlation effects and Cooper pairing in an ultracold Fermi gas with a negative scattering length on the formation rate of molecules is investigated. Cooper pairing is
