The authors show how the standard domain wall action can be simply modified to allow arbitrarily exact chiral symmetry at finite fifth dimensional extent. They note that the method can be used for both quenched and dynamical calculations. They test the method using smooth and thermalized gauge field configurations. They also make comparisons of the performance (cost) of the domain wall operator for spectroscopy compared to other methods such as the overlap-Dirac operator and find both methods are comparable in cost.
