TLDR
In this article, a variational procedure was used to study finite-density QCD in an approximation in which the interaction between quarks is modelled by that induced by instantons, and it was shown that uniform states with conventional chiral symmetry breaking have negative pressure with respect to empty space at all but the lowest densities.About:

The Universe in a Helium Droplet
TL;DR: In this article, the authors present a list of the top five most important categories of defense: 1. GRAVITY 7. MICROSCOPIC PHYSICS 13.2.

Non-perturbative renormalization flow in quantum field theory and statistical physics
TL;DR: In this paper, the use of exact renormalization group equation in quantum field theory and statistical physics is reviewed. But the authors focus on the second-order phase transition and the critical behavior of polymer chains, and do not consider the non-perturbative solutions of the coarse-grained free energy.

NJL-model analysis of dense quark matter
TL;DR: In this article, deconfined quark matter within NJL-type models are reviewed, focusing on the regime of low temperatures and moderate densities, which is not accessible by perturbative QCD.

Color-flavor locking and chiral symmetry breaking in high density QCD
TL;DR: In this paper, a symmetry breaking scheme for QCD with three massless quarks at high baryon density was proposed, where the color and flavor SU(3) color × SU (3) L × SU( 3) R symmetries were broken down to the diagonal subgroup SU(4) color+L + R by the formation of a condensate of quark Cooper pairs.

Dynamical Model of Elementary Particles Based on an Analogy with Superconductivity. II
Yoichiro Nambu,G. Jona-Lasinio +1 more
TL;DR: In this paper, a superconductive solution describing the proton-neutron doublet is obtained from a nonlinear spinor field Lagrangian, and the pions of finite mass are found as nucleon-antinucleon bound states by introducing a small bare mass into the Lagrangians which otherwise possesses a certain type of the ∆-ensuremath{gamma{5}$ invariance.

Computation of the quantum effects due to a four-dimensional pseudoparticle
TL;DR: In this paper, a detailed quantitative calculation is carried out of the tunneling process described by the Belavin-Polyakov-Schwarz-Tyupkin field configuration, where a certain chiral symmetry is violated as a consequence of the Adler-Bell-Jackiw anomaly.

Microscopic theory of superconductivity
TL;DR: In this paper, the key steps in the development of the microscopic understanding of superconductivity are discussed, and a detailed review of the main steps in this process is presented. But,

Superdense Matter: Neutrons Or Asymptotically Free Quarks?
John Collins,Malcolm J. Perry +1 more
TL;DR: The quark model implies that superdense matter (found in neutron star cores, exploding black holes, and the early big-bang universe) consists of quarks rather than of hadrons as discussed by the authors.

TL;DR: In this article, the derivation of gap equations and Ginzburg-Landau free energies for relativistic fermion systems is reviewed and the cases of superfluid neutron matter, superconducting electrons and superconducted and colour super-conducting quark matter are described in detail.
