Wigner–Weyl formalism and the propagator of Wilson fermions in the presence of varying external electromagnetic field
We develop Wigner–Weyl formalism for the lattice models. For the definiteness we consider Wilson fermions in the presence of U(1) gauge field. The given technique reduces calculation of the two point fermionic Green function to solution of the Groenewold equation. It relates Wigner transformation of...
