Gapless phases of color-superconducting matter
Igor A. Shovkovy, Stefan B. Ruester, Dirk H. Rischke
We discuss gapless color superconductivity for neutral quark matter in beta equilibrium at zero as well as at nonzero temperature. Basic properties of gapless superconductors are r…
Two lectures on color superconductivity
Igor A. Shovkovy
The first lecture provides an introduction to the physics of color superconductivity in cold dense quark matter. The main color superconducting phases are briefly described and the…
The gapless 2SC phase
Mei Huang, Igor A. Shovkovy
Recent results on the gapless 2SC phase are reviewed. These include: the thermal stability under the constraint of the local charge neutrality condition, the properties at zero and…
Screening masses in neutral two-flavor color superconductor
Mei Huang, Igor A. Shovkovy
The Debye and Meissner screening masses of the gluons and the photon in neutral and beta-equilibrated dense two-flavor quark matter are calculated. The results are presented in a g…
Chromomagnetic instability in dense quark matter
Mei Huang, Igor A. Shovkovy
The results for the Debye and Meissner screening masses of the gluons and the photon in the case of neutral and beta-equilibrated dense two-flavor quark matter are presented. In th…
Surprises in nonperturbative dynamics in sigma-model at finite density
V. P. Gusynin, V. A. Miransky, I. A. Shovkovy
The linear sigma-model occupies a unique place in elementary particle physics and quantum field theory. It has been recently realized that when a chemical…
Phase diagram of dense neutral three-flavor quark matter
Stefan B. Ruester, Igor A. Shovkovy, Dirk H. Rischke
We study the phase diagram of dense, locally neutral three-flavor quark matter as a function of the strange quark mass, the quark chemical potential, and the temperature, employing…
