Physical review A, 86(5), 053620-.||Series/Report no.:||Physical review A||Abstract:||We consider a mixture of two neutral cold Fermi gases with repulsive interactions. We show that in some region of the parameter space of the system the effective attraction between fermions of the same type can appear due to the exchange of collective excitations. This leads to the formation of BCS pairing in the case where bare interatomic interactions are repulsive.||URI:||https://hdl.handle.net/10356/95176
