Bose–Fermi N-polaron state emergence from correlation-mediated blocking of phase separation

Bose–Fermi N-polaron state emergence from correlation-mediated blocking of phase separation

We study N fermionic impurities in a one-dimensional lattice bosonic bath at unit filling. Using DMRG and mixed boundary conditions—periodic for bosons, open for fermions—we find an N-polaron ground state replacing phase separation at high interspecies repulsion. This tightly bound state of clustere...
