On the Weakness of Short-Range Interactions in Fermi Gases
arXiv:2201.04362 · doi:10.1007/s11005-022-01624-0
Abstract
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 Schrödinger operators with short-range pair interactions, where this approximation can be justified rigorously.
