标题： Collective excitations, instabilities, and ground state in dense quark matter

摘要： 我们研究了在(有能隙和无能隙)两味色超导相中光等离子体的谱及其与色磁不稳定性以及基态结构的联系。 结果表明，4-7和8胶子通道中的色磁不稳定性对应于两种非常不同的等离子体谱。 这些谱使我们得出关于基态中存在胶子凝聚态的明确结论（其中一些可能是空间非均匀的）。 我们还认为，在具有对应于无能隙颜色-味锁定态的奇异夸克质量的三味夸克物质中，应存在空间非均匀的胶子凝聚态。 显示英文摘要

摘要： We study the spectrum of light plasmons in the (gapped and gapless) two-flavor color superconducting phases and its connection with the chromomagnetic instabilities and the structure of the ground state. It is revealed that the chromomagnetic instabilities in the 4-7th and 8th gluonic channels correspond to two very different plasmon spectra. These spectra lead us to the unequivocal conclusion about the existence of gluonic condensates (some of which can be spatially inhomogeneous) in the ground state. We also argue that spatially inhomogeneous gluonic condensates should exist in the three-flavor quark matter with the values of the mass of strange quark corresponding to the gapless color-flavor locked state.
