Ferromagnetic condensation in high density hadronic matter    [PDF]

Henrik Bohr, Prafulla K. Panda, Constanca Providencia, Joao da Providencia

It is shown under which conditions, at very high densities, such as those that may be found in the interior of a neutron star, a ferromagnetic phase transition could occur, induced by a four fermion interaction analogous to the one which is responsible for chiral symmetry breaking in the Nambu-Jona-Lasinio model.
