Chiral Separation Effect in lattice regularization

Understand

We consider Chiral Separation Effect (CSE) in the lattice regularized quantum field theory.

• We discuss two types of regularization - with and without exact chiral symmetry.
• In the latter case this effect is described by its conventional expression for the massless fermions.
• This is illustrated by the two particular cases - of Wilson fermions and of the conventional overlap fermions.
