* ABSTRACT
We study crystalline color superconductivity, which may arise in
quark matter due to the mismatch between Fermi surfaces of
different quark flavors. Using Schwinger-Dyson equations derived
from an effective theory of low-energy quasiparticles, we examine
both the case of an effective four Fermi interaction (appropriate
for intermediate densities, such as those found in a neutron star)
and Landau-damped one gluon exchange (appropriate for asymptotic
density). We discuss patching together regions of plane-wave
(LOFF) condensation, which in some cases can lower the vacuum
energy substantially. Finally, we discuss the energy of the
crystalline phase compared to that of the single flavor (uu, dd)
condensate phase.
