QCD-like theories at finite baryon density
John B. Kogut,M. A. Stephanov,M. A. Stephanov,D. Toublan,Jacobus J. M. Verbaarschot,Ariel R. Zhitnitsky +5 more
TL;DR: In this paper, a second order phase transition occurs at a value of μ equal to half the mass of the Goldstone modes of a spontaneously broken enlarged chiral symmetry group, where the lightest baryons are diquarks.

QCD-like Theories at Finite Baryon Density
John B. Kogut,M. A. Stephanov,M. A. Stephanov,D. Toublan,Jacobus J. M. Verbaarschot,Ariel R. Zhitnitsky +5 more
TL;DR: In this article, the authors derived the low-energy effective Lagrangian for pseudoreal fermions at finite baryon density and showed that the lightest baryons are diquarks, together with pseudoscalar mesons, the Goldstone modes of a spontaneously broken enlarged chiral symmetry group.

Quenched lattice QCD at finite isospin density and related theories
John B. Kogut,D.K. Sinclair +1 more
TL;DR: In this paper, the scaling properties near the critical point using effective (chiral) Lagrangians were studied and evidence for scaling with mean-field critical exponents in each case.

Quark-meson-diquark model for two-color QCD
TL;DR: In this article, a two-flavor quark-meson-diquark model for two-color QCD and its extensions to include gauge-field dynamics as described by the Polyakov loop is introduced.

Hybrid Monte Carlo
TL;DR: In this article, a hybrid (molecular dynamics/Langevin) algorithm is used to guide a Monte Carlo simulation of lattice field theory, which is especially efficient for quantum chromodynamics which contain fermionic degrees of freedom.

On the phase structure of vector-like gauge theories with massless fermions
Thomas Banks,A. Zaks +1 more
TL;DR: In this article, the authors present a systematic expansion for studying an infrared-stable fixed point of gauge theories with massless fermions and show that the transition between chirally symmetric and asymmetric phases is generally first order.

QCD at finite baryon density: nucleon droplets and color superconductivity
TL;DR: 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.

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.

Diquark Bose condensates in high density matter and instantons
TL;DR: In this paper, an interesting toy model is provided by QCD with two colors: it has a particle-antiparticle symmetry which relates {l_angle}{bar q}q{r_angle} and {l _angle}qq{r-angle} condensates.
