The main goal has been to investigate the "magnetic catalysis" for the nuclear matter under a strong magnetic field. That is the magnetic-field-dependence of the Dirac-sea contribution, which had been omitted in previous studies about magnetized nuclear matter, but must be taken into account in very similar studies about quark matter.
Two models are used: Walecka and extended linear-sigma models.
If one ignores the effect of magnetic catalysis, creating nuclear matter becomes energetically profitable in a magnetic field, indicating an increased binding energy. HOWEVER, if magnetic catalysis is properly taken into account, its effect dominates at large magnetic field, and creating nuclear matter becomes energetically MORE costly, even though the binding energy is further increased.
The calculation isolates the effect of magnetic catalysis, but it has to be kept in mind that there are more effects that have been omitted.
