Weyl and ghost fermions on the lattice
Artan Borici
Nielsen-Ninomiya theorem forbids Weyl fermions on the lattice which respect the full hypercubic symmetry. By giving up this assumption in a specific way, it is possible to formulat…
Creutz Fermions on an Orthogonal Lattice
Artan Borici
In a recent paper, Creutz has given a new action describing two species of Dirac fermions with exact chiral symmetry on the lattice. This action depends on a parameter which may be…
A Schur Complement Approach to Chiral Fermions
Artan Borici
Lattice chiral fermions are synonymous to the Ginsparg-Wilson relation. Indeed, this relation is satisfied by the overlap, domain wall and perfect action fermion kernel. In a recen…
On Gauged Renormalisation Group Transformations of Lattice Fermions
Artan Borici
We construct a hierarchy of lattice fermions, where the coarser lattice Dirac operator is the Schur complement of the block UL decomposition of the finer lattice operator. We show…
Speeding up Domain Wall Fermion Algorithms using QCDLAB
Artan Borici
Simulating lattice QCD with chiral fermions and indeed using Domain Wall Fermions continues to be challenging project however large are concurrent computers. One obvious bottleneck…
QCDLAB: Designing Lattice QCD Algorithms with MATLAB
Artan Borici
This paper introduces QCDLAB, a design and research tool for lattice QCD algorithms. The tool, a collection of MATLAB functions, is based on a ``small-code'' and a ``minutes-run-ti…
