Title: Chiral properties of the QCD vacuum in ultrastrong magnetic fields: A Nambu-Jona-Lasinio model with a semiclassical approximation

Abstract

The breaking of chiral symmetry of light quarks at zero temperature in the presence of strong quantizing magnetic field is studied using a Nambu-Jona-Lasinio (NJL) model with a Thomas-Fermi-type semiclassical formalism. It is found that the dynamically generated light quark mass can never become zero if the Landau levels are populated and increases with the increase of magnetic field strength.

  • We study the two-flavor Nambu-Jona-Lasinio model with the Polyakov loop in the presence of a strong magnetic field and a chiral chemical potential {mu}{sub 5}, which mimics the effect of imbalanced chirality due to QCD instanton and/or sphaleron transitions. First, we focus on the properties of chiral symmetry breaking and deconfinement crossover under the strong magnetic field. Then we discuss the role of {mu}{sub 5} on the phase structure. Finally, the chirality charge, electric current, and their susceptibility, which are relevant to the chiral magnetic effect, are computed in the model.
  • A possibility of formation of static dual scalar and pseudoscalar density wave condensates in dense quark matter is considered for the Nambu-Jona-Lasinio model in an external magnetic field. Within a mean-field approximation, the effective potential of the theory is obtained and its minima are numerically studied; a phase diagram of the system is constructed. It is shown that the presence of a magnetic field favors the formation of spatially inhomogeneous condensate configurations at low temperatures and arbitrary nonzero values of the chemical potential.
  • We discuss the mechanism of dynamical breaking of chiral symmetry and pion properties in the Nambu and Jona-Lasinio model. A covariant as well as a noncovariant formalism have been used.
  • Using an extended Nambu-Jona-Lasinio model as a low-energy effective model of QCD, we show that the vacuum in a strong external magnetic field (stronger than 10{sup 16} T) experiences a spontaneous phase transition to an electromagnetically superconducting state. The unexpected superconductivity of, basically, empty space is induced by emergence of quark-antiquark vector condensates with quantum numbers of electrically charged rho mesons. The superconducting phase possesses an anisotropic inhomogeneous structure similar to a periodic Abrikosov lattice in a type-II superconductor. The superconducting vacuum is made of a new type of vortices which are topological defects in the charged vector condensates. Themore » superconductivity is realized along the axis of the magnetic field only. We argue that this effect is absent in pure QED.« less
  • In the present work we use the large-N{sub c} approximation to investigate quark matter described by the SU(2) Nambu-Jona-Lasinio model subject to a strong magnetic field. The Landau levels are filled in such a way that usual kinks appear in the effective mass and other related quantities. {beta} equilibrium is also considered and the macroscopic properties of a magnetar described by this quark matter is obtained. Our study shows that the magnetar masses and radii are larger if the magnetic field increases but only very large fields ({>=}10{sup 18} G) affect the equation of state in a non-negligible way.
