Gauge field fluctuations and first-order phase transition in color superconductivity.
نویسندگان
چکیده
We study the gauge field fluctuations in dense quark matter and determine the temperature of the induced first-order phase transition to the color-superconducting phase in weak coupling. We find that the local approximation of the coupling between the gauge potential and the order parameter, employed in the Ginzburg-Landau theory, has to be modified by restoring the full momentum dependence of the polarization function of gluons in the superconducting phase.

Thermal fluctuations of gauge fields and first order phase transitions in color superconductivity
We study the effects of thermal fluctuations of gluons and the diquark pairing field on the superconducting-to-normal state phase transition in a three-flavor color superconductor, using the Ginzburg-Landau free energy. At high baryon densities, where the system is a type I superconductor, gluonic fluctuations, which dominate over diquark fluctuations, induce a cubic term in the Ginzburg-Landau...
متن کاملCritical Line for H-Superfluidity in Strange Quark Matter?
In QCD, there is a phase transition to a color superconducting phase at high quark density and low temperature [1–24]. At densities of interest for the collisions of heavy ions or quark stars, “2+1” flavors of quarks — up, down, and strange — enter. The order of the phase transition to a color superconducting phase at zero temperature, as function of the quark chemical potential, was analyzed p...

We study thermal phase transitions of color superconductivity by the lattice simulations of the Ginzburg-Landau (GL) effective theory. The theory is equivalent to the SUf(3) × SUc(3) Higgs model coupled to SUc(3) color gauge fields. From the eigenvalues of a 3×3 gauge-invariant diquark composite, a clear distinction between the 2-flavor color superconductivity (2SC) and the color flavor locking...

A model for spin-charge separated superconductivity in two dimensions is introduced where the phases of the spinon and holon order parameters couple gauge-invariantly to a statistical gauge-field representing chiral spin-fluctuations. The model is analyzed in the continuum limit and in the low-temperature limit. In both cases we find that physical electronic phase correlations show a supercondu...
متن کاملAnalytic Estimate of the Order Parameter for Magnetic Charge Condensation in Qcd
A possible mechanism for confinement of color is Dual Superconductivity of the Vacuum 1 2 3. The idea is that magnetic charges condense in the vacuum : the chromoelectric field acting between a q− q̄ pair is channeled by dual Meissner effect into flux tubes with energy proportional to the distance. Flux tubes are indeed observed in lattice simulations , and the corresponding field configurations...
