Crystalline color superconductors

Understand

Inhomogeneous superconductors and inhomogeneous superfluids appear in a variety of contexts including quark matter at extreme densities, fermionic systems of cold atoms, type-II cuprates, and organic superconductors.

• In the present review the focus is on properties of quark matter at high baryonic density, which may exist in the interior of compact stars.
• The conditions realized in these stellar objects tend to disfavor standard symmetric BCS pairing and may favor an inhomogeneous color superconducting phase.
• The properties of inhomogeneous color superconductors are discussed in detail and in particular of crystalline color superconductors.
