Quark mass effects on the stability of hybrid stars
M. Buballa, F. Neumann, M. Oertel +1
We perform a study of the possible existence of hybrid stars with color superconducting quark cores using a specific hadronic model in a combination with an NJL-type quark model. I…
Neutral Dense Quark Matter
Mei Huang, Igor Shovkovy
The ground state of dense up and down quark matter under local and global charge neutrality conditions with -equilibrium has at least four possibilities: normal, regular 2SC, ga…
Spontaneous rotational symmetry breaking and roton like excitations in gauged sigma-model at finite density
V. P. Gusynin, V. A. Miransky, I. A. Shovkovy
The linear -model with a chemical potential for hypercharge is a toy model for the description of the dynamics of the kaon condensate in high density QCD. We analyze the dynamic…
Two flavor color superconductivity and compact stars
Igor Shovkovy, Matthias Hanauske, Mei Huang
Baryonic matter at high density and low temperature is a color superconductor. In real world, this state of matter may naturally appear inside compact stars. A construction of a hy…
Gapless color superconductivity at zero and at finite temperature
Mei Huang, Igor Shovkovy
We present a detailed study of the recently proposed gapless color superconductivity in neutral two-flavor quark matter in beta-equilibrium at zero as well as at finite temperature…
Large N dynamics in QED in a magnetic field
V. P. Gusynin, V. A. Miransky, I. A. Shovkovy
The expression for the dynamical mass of fermions in QED in a magnetic field is obtained for a large number of the fermion flavor N in the framework of 1/N expansion. The existence…
Fractal structure of the effective action in (quasi-) planar models with long-range interactions
E. V. Gorbar, V. P. Gusynin, V. A. Miransky +1
We derive the effective potential for composite fields in a class of (quasi-) planar models with long-range interactions. This class of models can be relevant for high temperature…
Impact of CFL Quark Matter on the Cooling of Compact Stars
Igor A. Shovkovy, Paul J. Ellis
The cooling mechanism of compact stars with quark cores in the color-flavor locked phase is discussed. It is argued that the high thermal conductivity of the quark core plays a key…
Nonstrange hybrid compact stars with color superconducting matter
Igor Shovkovy, Matthias Hanauske, Mei Huang
Realistic nonstrange hybrid compact stars with color superconducting quark matter in their interior are constructed. It is shown that a positively charged two-flavor color supercon…
Gapless two-flavor color superconductor
Igor Shovkovy, Mei Huang
A new, gapless two-flavor color superconducting phase that appears under conditions of local charge neutrality and -equilibrium is revealed. In this phase, the symmetry of the g…
