“…The number of generations in the dynamical symmetry-breaking scenario, proposed in [13] to obtain massive fermions without low-energy Higgs particles, is the same as in the genuine Calabi-Yau compactification, but the low-energy particle spectrum is more complicated. Nevertheless, the conclusions are similar to those drawn above.…”

“…Conversely, quantum effects of matter fields determine the vacuum expectation value of the Wilson loop. Symmetry breaking by Wilson loops, not only on a torus space [10,11,12,13,14,15,16,17,18,19,20,21,22] but also on a nonsimply connected lens space [23,24,25,26,27,28], has been considered and used in unified models of gauge theories in higher (more than four) dimensions. Other approaches to the mechanism in string theories in novel ways are found in refs.…”

We investigate the effect of finite fermion density on symmetry breaking by Wilson loops in (1 + 1) dimensions. We find the breaking and restoration of symmetry at finite density in the models with SU (2) and SU (3) gauge symmetries, in the presence of the adjoint fermions. The transition can occur at a finite density of fermions, regardless of the periodic or antiperiodic boundary condition of the fermion field; this is in contrast to the finite-temperature ease examined by Ho and Hosotani (Nucl. Phys. B345 (1990) 445) where the boundary condition of fractional twist is essential to the occurrence of the phase transition.
