Recent soliton solutions in a charge-density-wave condensate in both the incommensurate and the commensurate half-filled band are considered. Neutral solitons exist in both cases while the charged soliton exists only in the commensurate case. Inclusion of exchange Coulomb interaction leads to a complex order parameter and then the charged solitons become phase solitons.
