Abstract

The Debye and Meissner screening masses of the gluons and the photon in neutral and \ensuremathβ-equilibrated dense two-flavor quark matter are calculated. The results are presented in a general form that can be used in gapped as well as gapless color superconducting phases. The results for the magnetic screening masses indicate that the system develops a chromomagnetic instability. Possible consequences of the instability are discussed.
