Dense Quark Matter in a Magnetic Field
We explore the effects of an applied strong external magnetic field in the structure and magnitude of the color superconducting diquark condensate of a three massless flavor theory. The long-range component of the B field that penetrates the superconductor enhances the condensates formed by quarks charged with respect to this electromagnetic field.
متن کاملQuark Condensate in a Magnetic Field
We study the dependence of quark condensate Σ on an external magnetic field. For weak fields, it rises linearly: Σ(H) = Σ(0)
متن کاملOrigin of magnetic field in compact stars and magnetic properties of quark matter
Microscopic origin of the magnetic field observed in compact stars is studied in quark matter. Spontaneous spin polarization appears in high-density region due to the Fock exchange term. On the other hand, quark matter becomes unstable to form spin density wave in the moderate density region, where restoration of chiral symmetry plays an important role. Coexistence of the magnetism and color su...
متن کاملNeutron star matter in the quark-meson coupling model in strong magnetic fields
P. Yue and H. Shen Department of Physics, Nankai University, Tianjin 300071, China Abstract The effects of strong magnetic fields on neutron star matter are investigated in the quark-meson coupling (QMC) model. The QMC model describes a nuclear many-body system as nonoverlapping MIT bags in which quarks interact through self-consistent exchange of scalar and vector mesons in the mean-field appr...
متن کاملMagnetic Phases in Dense Quark Matter
In this paper I discuss the magnetic phases of the three-flavor color superconductor. These phases can take place at different field strengths in a highly dense quark system. Given that the best natural candidates for the realization of color superconductivity are the extremely dense cores of neutron stars, which typically have very large magnetic fields, the magnetic phases here discussed coul...
