In-medium bound states of two bosonic impurities in a one-dimensional Fermi gas
We investigate the ground-state energy of throwing stars a one-dimensional Fermi gas with two bosonic impurities.We consider spinless fermions with no fermion-fermion interactions.The fermion-impurity and impurity-impurity interactions are modeled with Dirac delta functions.First, we study the case where impurity and fermion have equal masses, and
