Htc. Stoof et al., THEORY OF INTERACTING QUANTUM CASES, Journal of research of the National Institute of Standards and Technology, 101(4), 1996, pp. 443-455
We present a unified picture of the interaction effects in dilute atom
ic quantum gases. We consider fermionic as well as bosonic gases and,
in particular, discuss for both forms of statistics the fundamental di
fferences between a gas with effectively repulsive and a gas with effe
ctively attractive inter atomic interactions, i.e., between a gas with
either a positive or a negative scattering length.
