English abstract:
We study the influence of strong magnetic fields on the first order phase transition to nuclear
matter in the Walecka model. Magnetic fields that are sufficiently strong might be realized in the core of
magnetars as well as in neutron star mergers. We show that the naive renormalization prescription
commonly utilized in the mean field approximation of the Walecka model ignores important effects that lead
to a qualitative as well as quantitative behavior of the phase transition, which is in stark contrast to what has
been observed in the literature so far. Formally, this is closely related to the socalled magnetic catalysis
known in the context of spontaneous chiral symmetry breaking.
Keywords:
nuclear matter, magnetic catalysis, spontaneous symmetry breaking
