Contribution

It analyzes the feasibility of applying Chiu's quasi-optimal domain wall fermions to the original variant and comments on their use in dynamical simulations.

Findings

Feasibility of implementing Chiu's proposal for original domain wall fermions.

Insights into dynamical simulations with ultraviolet suppressed fermions.

Potential reduction in computational complexity for lattice QCD simulations.

Abstract

In a recent work Chiu proposed to modify domain wall fermions that allow in an optimal way fewer number of flavors than in the standard case. This is done using a variant of doamin wall fermions, the so-called truncated overlap fermions. In this note I discuss the possibility to implement his proposal for the original variant of domain wall fermions. I make also some remarks on dynamical simulations with ultraviolet suppressed domain wall fermions.
