“…In that Section, we deferred all discussion of methods by which the gap ∆, which characterizes the ground state, is calculated. Much effort has gone into calculating the magnitude of the gaps in the 2SC and CFL phases, 4,5,6,7,13,17,43,57,58,59,45,60,9,61,62,63,64,65,66,11,12,67,68,69,70 and in this section we face up to the challenge of describing what has been learned.…”

Important progress in understanding the behavior of hadronic matter at high density has been achieved recently, by adapting the techniques of condensed matter theory. At asymptotic densities, the combination of asymptotic freedom and BCS theory make a rigorous analysis possible. New phases of matter with remarkable properties are predicted. They provide a theoretical laboratory within which chiral symmetry breaking and confinement can be studied at weak coupling. They may also play a role in the description of neutron star interiors. We discuss the phase diagram of QCD as a function of temperature and density, and close with a look at possible astrophysical signatures.

“…In fact, current weak-coupling calculations cannot be extrapolated below about 10 8 MeV because of gauge dependence arising from the neglect of vertex corrections (19). There have also been some preliminary investigations of confinement-related physics such as a gluon condensate (20,21).…”

“…For instance, according to the modern point of view, the color superconducting (CSC) phenomenon can be realized in neutron star cores (see the reviews [4]). However, according to [17], the critical parameters of this phase transition strongly depend on the value of the gluon condensate (in this case, only its chromomagnetic component survives). Moreover, it turns out that even for a rather weak quark coupling, different external chromomagnetic field configurations induce the CSC phenomenon [18].…”

Quark and pion condensation in a chromomagnetic background field

et al. 2006

The general features of quark and pion condensation in dense quark matter with flavor asymmetry have been considered at finite temperature in the presence of a chromomagnetic background field modelling the gluon condensate. In particular, pion condensation in the case of a constant abelian chromomagnetic field and zero temperature has been studied both analytically and numerically. Under the influence of the chromomagnetic background field the effective potential of the system is found to have a global minimum for a finite pion condensate even for small values of the effective quark coupling constant. In the strong field limit, an effective dimensional reduction has been found to take place.
