Self-binding of one-dimensional fermionic mixtures with zero-range interspecies attraction
J. Givois, A. Tononi, D. S. Petrov
For sufficiently large mass ratios the attractive exchange force caused by a single light atom interacting with a few heavy identical fermions can overcome their Fermi degeneracy p…

Binding of heavy fermions by a single light atom in one dimension
A. Tononi, J. Givois, D. S. Petrov
We consider the problem of identical fermions interacting via a zero-range attractive potential with a lighter atom in one dimension. Using the few-body approach based on the S…
