Phys. Rev. D 62, 025022 (2000) [5 pages]Chiral symmetry in the linear sigma model in a magnetic environmentReceived 4 October 1999; published 27 June 2000 We study the chiral symmetry structure in a linear sigma model with fermions in the presence of an external, uniform magnetic field in the “effective potential” approach at the one loop level. We also study the chiral phase transition as a function of density in the core of magnetized neutron stars. © 2000 The American Physical Society URL:
