Pion/axion domain wall in the presence of the magnetic fields and chiral asymmetry †

Kohei Kamada †

I will introduce the chiral soliton lattice which is the layer of the pion/axion domain walls
in the presence of the chiral chemical potential and magnetic fields.
If my preparation goes well, I will try to explain how it could appear in the compact stars
and what happens if they have boundaries.
