Abstract

We elucidate magnetic effects in the skyrmion system to probe into the dense nuclear matter. We find a deformed π0 dipole structure of a baryon induced by a magnetic field. We then extend our scope to stacked Skyrme crystal layers to scrutinize phases of magnetized nuclear matter. We observe a quantized magnetic flux and identify a phase transition from a crystalline state to a π0 domain wall corresponding to a topological transmutation from π3(S3) to π1(S1). We establish the phase diagram, which could be explored also in analogous systems with two-component Bose-Einstein condensates.
