In the model of three-phase chiral quark bags in $(1+1)$ dimensions, we obtain self-consistent solutions describing the system of two interacting bags. Attention is focused on investigating the role played by the fermionic vacuum polarization inside the bags in the dynamics of the system; the bosonic field interrelating the bags is taken into account only at the one-meson exchange level. The renormalized total energy of the system is investigated as a function of parameters characterizing the geometry of the problem and of the additional bag characteristics arising in $(1+1)$ dimensions. We show that in the system of two three-phase bags, vacuum polarization yields a strong nonlinear interaction at small distances, which can be either repulsive or attractive depending on the bag characteristics.
Keywords: hybrid chiral bag models, Dirac sea polarization effects.
