We argue that the chiral symmetry breaking/restoration in cold, confining dense quark matter, called “quarkyonic” matter, whose presence is expected to be relevant for intermediate density region of the phase diagram. Although bulk properties of the quark matter is roughly described by deconfined quarks, the excitations near the Fermi surface is strongly affected by the confining correlation. We will show that such strong infrared correlations induce the chiral spiral, i.e., the spatial modulation of the chiral condensate. It breaks the chiral symmetry locally but restores it globally, naturally connecting chiral symmetry broken phase and restored phase.
