Medium-induced bosonic clusters in a Bose-Fermi mixture: Towards simulating cluster formations in neutron-rich matter

Understand

Considering bosonic atoms immersed in a dilute Fermi gas, we theoretically investigate medium-induced bosonic clusters associated with fermion-mediated two- and three-body interactions.

• Using the variational approach combined with the fermion-mediated interactions, we numerically calculate the binding energies of two- and three-body bosonic clusters in a one-dimensional system.
• It is found that the bosonic clusters can be formed even with a repulsive boson-boson interaction due to the fermion-mediated interactions.
• Our results would be relevant for ultracold atomic systems as well as analogue quantum simulations of alpha clusters in neutron-rich matter.
