Wilson, fixed point and Neuberger's lattice Dirac operator for the Schwinger model
We perform a comparison between different lattice regularizations of the Dirac operator for massless fermions in the framework of the single and two flavor Schwinger model. We consider a) the Wilson-Dirac operator at the critical value of the hopping parameter: b) Neuberger's overlap operator: c) the fixed point operator. We test chiral properties of the spectrum. dispersion relations and rotational invariance of the mesonic bound state propagators.
