Polarizing the medium: Fermion-mediated interactions between bosons
DC Zheng, CR Ye, L Wen, R Liao - Physical Review A, 2021 - APS
We consider a homogeneous mixture of bosons and polarized fermions. We find that long-
range and attractive fermion-mediated interactions between bosons have dramatic effects …
