Progress using generalized lattice Dirac operators to parametrize the Fixed-Point QCD action
P. Hasenfratz, S. Hauswirth, K. Holland +3
We report on an ongoing project to parametrize the Fixed-Point Dirac operator for massless quarks, using a very general construction which has arbitrarily many fermion offsets and…
The Perfect Laplace Operator for Non-Trivial Boundaries
S. Hauswirth
The application of Renormalization Group (RG) methods to find perfect discretizations of partial differential equations is a promising but little investigated approach. We calculat…
The construction of generalized Dirac operators on the lattice
P. Hasenfratz, S. Hauswirth, K. Holland +3
We discuss the steps to construct Dirac operators which have arbitrary fermion offsets, gauge paths, a general structure in Dirac space and satisfy the basic symmetries (gauge symm…
Perfect discretizations of differential operators
S. Hauswirth
We investigate an approach for the numerical solution of differential equations which is based on the perfect discretization of actions. Such perfect discretizations show up at the…
