Chiral asymmetry in cold QED plasma in a strong magnetic field

Understand

The interaction induced chiral asymmetry is calculated in cold QED plasma beyond the weak-field approximation.

• By making use of the recently developed Landau-level representation for the fermion self-energy, the chiral shift and the parity-even chiral chemical potential function are obtained with the help of numerical methods.
• The results are used to quantify the chiral asymmetry of the Fermi surface in dense QED matter.
• Because of the weakness of the QED interactions, the value of the asymmetry appears to be rather small even in the strongest magnetic fields and at the highest stellar densities.
