Description

We explore the phase diagram of the 1+1 dimensional Gross-Neveu model at finite number of fermion flavors using lattice field theory. Besides a chirally symmetric phase and a homogeneously broken phase we find clear evidence for the existence of an inhomogeneous phase, where the chiral condensate is a spatially oscillating function. We present numerical results for the phase diagram and visualize the shape of the expectation value of the chiral condensate in the inhomogeneous phase.
