Query: Induced magnetic moment in the magnetic catalysis of chiral symmetry
  breaking   The chiral symmetry breaking in a Nambu-Jona-Lasinio effective model of
quarks in the presence of a magnetic field is investigated. We show that new
interaction tensor channels open up via Fierz identities due to the explicit
breaking of the rotational symmetry by the magnetic field. We demonstrate that
the magnetic catalysis of chiral symmetry breaking leads to the generation of
two independent condensates, the conventional chiral condensate and a spin-one
condensate. While the chiral condensate generates, as usual, a dynamical
fermion mass, the new condensate enters as a dynamical anomalous magnetic
moment in the dispersion of the quasiparticles. Since the pair, formed by a
quark and an antiquark with opposite spins, possesses a resultant magnetic
moment, an external magnetic field can align it giving rise to a net magnetic
moment for the ground state. The two condensates contribute to the effective
mass of the LLL quasiparticles in such a way that the critical temperature for
chiral symmetry restoration becomes enhanced.
