In this paper we derive the general expression of a one-loop effective potential of the nonintegrable phases of Wilson lines for an SU(N) gauge theory with a massless adjoint fermion defined on the spactime manifold R^1,d\ensuremath-3\ifmmode×\else\texttimes\fiT2 at finite temperature and fermion density. The phase structure of the vacuum is presented for the case with d=4 and N=2 at zero temperature. It is found that gauge symmetry is broken and restored alternately as the fermion density increases, a feature not found in the Higgs mechanism. It is the manifestation of the quantum effects of the nonintegrable phases.
