摘要：
Ultracold quantum gases of equal-spin fermions with short-range interactions are often considered free even in the presence of strongly binding spin-up-spin-down pairs. We describe a large class of many-particle Schrodinger operators with short-range pair interactions, where this approximation can be justified rigorously.
