Spectral properties and chiral symmetry violations of (staggered) domain wall fermions in the Schwinger model

We follow up on a suggestion by Adams and construct explicit domain wall fermion operators with staggered kernels. We compare different domain wall formulations, namely the standard construction as well as Boriçi’s modified and Chiu’s optimal construction, utilizing both Wilson and staggered kernels...

We compare different domain wall formulations, namely the standard construction as well as Boriçi’s modified and Chiu’s optimal construction, utilizing both Wilson and staggered kernels. In the process, we generalize the staggered kernels to arbitrary even dimensions and introduce both truncated and optimal staggered domain wall fermions. Some numerical investigations are carried out in the (1+1)-dimensional setting of the Schwinger model, where we explore spectral properties of the bulk, effective and overlap Dirac operators in the free-field case, on quenched thermalized gauge configurations and on smooth topological configurations.
