     Particle Formation and Ordering in Strongly Correlated Fermionic
           Systems: Solving a Model of Quantum Chromodynamics


We study a (1+1)-dimensional version of the famous Nambu-Jona-Lasinio
model of Quantum Chromodynamics (QCD2) both at zero and finite matter
density using non-perturbative techniques such as non-Abelian
bosonization and Truncated Conformal Space Approach.
At zero density we describe a formation of fermion three-quark
(nucleons and Delta-baryons) and boson (two-quark mesons, six-quark
deuterons) bound states and also a formation of a topologically
nontrivial phase. At finite matter density, the model has a rich phase
diagram which includes phases with density wave and superfluid
quasi-long-range (QLR) order and also a phase of a baryon
Tomonaga-Luttinger liquid (strange metal).
The QLR order results as a condensation of scalar mesons
(the density wave) or six-quark bound states (deuterons).
