  We study the Dual Chiral Density Wave (DCDW) in nuclear matter using a
hadronic model with the parity doublet structure. We first extend the ordinary
DCDW ansatz so as to incorporate the effect of an explicit chiral symmetry
breaking. Then via numerically evaluating and minimizing the effective
potential, we determine the phase structure. We find, in addition to the
ordinary DCDW phase where the space average of the chiral condensate vanishes,
a new DCDW phase (sDCDW) with a nonvanishing space average depending on the
value of the chiral invariant mass parameter.
