Abstract: Unusual chiral properties of the ground state of relativistic matter in a strong magnetic field will be discussed. The main emphasis will be placed on the dynamical generation of the chiral shift in different types of stellar matter. From the physics viewpoint, the chiral shift determines a relative shift of the longitudinal momenta (along the direction of the magnetic field) in the dispersion relations of opposite chirality fermions. The resulting ground state is characterized by a chiral asymmetry at the Fermi surface that is expected to affect the low-energy physics in compact stars. Several aspects of such physics will be discussed.he result of type I starquakes due to, simply, a change of stellar ellipticity.
