  报告摘要：In a nuclear system with chiral symmetry and a magnetic field, SU(2) symmetry is explicitly broken down to U(1), and the baryon number winding should be changed accordingly. I will first discuss deformation of isolated baryons in a magnetic field and explain two interesting observations; the magnetic assisted confinement and the mass splitting between protons and neutrons by a topological term. I will next discuss the Skyrme Crystals under a magnetic field and show two solutions. One corresponds to deformed nuclear matter and the other to the uniform pionic domain wall. I will finally show the phase diagram as a function of the density and the magnetic field.
