A quantum field theory of crystals. III

A two-band model is considered in one-dimensional fermion systems. The particle-hole pairs are favourable for our symmetry bands and the positive value of the two-body potential. The boson condensations of the particle-hole pairs are expected to form crystals. The gapless boson spectrum is shown to be proportional to a linear momentum.
