Chromomagnetic Instability and Gluonic Phase in Dense Neutral Quark Matter
The phase structure of hot and/or dense QCD is one of the most exciting current topics in the field of strong interactions. In particular, the properties of cold and dense quark matter are of great interest in astrophysics and cosmology; it is now widely accepted that, at moderate densities of relevance for the interior of compact stars, quark matter is a color superconductor and has a rich pha...
متن کاملChromomagnetic Instability and Gluonic Phase *
It has been suggested that quark matter might exist inside central regions of compact stars. At sufficiently high baryon density, cold quark matter is expected to be in a color superconducting (CSC) state. This is one of the reasons why the color superconductivity has been intensively studied. Bulk matter in the compact stars must be in β-equilibrium and be electrically and color neutral. The e...
متن کاملNeutral Dense Quark Matter
The ground state of dense up and down quark matter under local and global charge neutrality conditions with β-equilibrium has at least four possibilities: normal, regular 2SC, gapless 2SC phases, and mixed phase composed of 2SC phase and normal components. The discussion is focused on the unusual properties of gapless 2SC phase at zero as well as at finite temperature.
متن کاملChromomagnetic Instability and Gluonic Phase at Nonzero Temperature
We describe the results of recent studies of a chromomagnetic instability and a gluonic phase in neutral two-flavor quark matter at nonzero temperature.
متن کاملChromomagnetic instability in two-flavor quark matter at nonzero temperature
We calculate the effective potential of the 2SC/g2SC phases including vector condensates (〈gA z 〉 and 〈gA z 〉) and study the gluonic phase and the single plane-wave Larkin-Ovchinnikov-Fulde-Ferrell state at nonzero temperature. Our analysis is performed within the framework of the gauged Nambu–Jona-Lasinio model. We compute potential curvatures with respect to the vector condensates and investi...
