摘要
A new class of domain wall fermions is defined that interpolates between Shamir's and Borici's form without increasing the number of Dirac applications per CG iteration. This class represents a full (real) Mobius transformation of the Wilson kernel. Simulations on quenched Wilson lattices with beta = 6.0 show that the number of lattice sites (L-s) in the fifth dimension can be reduced by a factor of 2 or more at fixed value of chiral symmetry violations measured by the residual mass (m(res)).
