  I discuss some properties of spatially dependent chiral condensates, focusing
on one-dimensional modulations. After briefly introducing a generic formalism
for studying inhomogeneous solutions in dense quark matter, I consider a
plane-wave and a sinusoidal ansatz, and discuss the relationship between their
order parameters and free energies, as well as a comparison of their dispersion
relations. I then introduce a real kink crystal, and discuss its relationship
with the sinusoidal ansatz by performing a Fourier analysis of this kind of
solution.
