Baryons in the Gross-Neveu model in 1+1 dimensions at finite number of flavors

In a recent work [J. Lenz et al., Phys. Rev. D 101,094512 (2020)] we studied the phase structure of the Gross-Neveu (GN) model in 1 + 1 dimensions at finite number of fermion flavors N-f = 2,8,16, finite temperature and finite chemical potential using lattice field theory. Most importantly, we found an inhomogeneous phase at low temperature and large chemical potential, quite similar to the analytically solvable N-f -> infinity limit. In the present work we continue our lattice field theory investigation of the finite-N-f GN model by studying the formation of baryons, their spatial distribution and their relation to the chiral condensate. As a preparatory step we also discuss a linear coupling of lattice fermions to the chemical potential.
