Quarkyonic Matter: basic ideas and recent developments

In this seminar I will review properties of QCD with large number of colors and the way it led to the Quarkyonic Matter phase, in which confinement cooperates with chiral symmetry restoration. Recent investigations along this line have shown that for large chemical potentials the Fermi sea is unstable against formation of a spatially nonuniform condensate which breaks chiral symmetry but in a different way than in vacuum. The possibility of Quarkyonic Matter in the 't Hooft model will be shortly discussed.
