  We investigate spin-charge separation of a spin-1/2 Fermi system confined in
a triple well where multiple bands are occupied. We assume that our finite
fermionic system is close to fully spin polarized while being doped by a hole
and an impurity fermion with opposite spin. Our setup involves ferromagnetic
couplings among the particles in different bands, leading to the development of
strong spin-transport correlations in an intermediate interaction regime.
Interactions are then strong enough to lift the degeneracy among singlet and
triplet spin configurations in the well of the spin impurity but not strong
enough to prohibit hole-induced magnetic excitations to the singlet state.
Despite the strong spin-hole correlations, the system exhibits spin-charge
deconfinement allowing for long-range entanglement of the spatial and spin
degrees of freedom.
