Lattice theories of chiral fermions.
We present a Hamiltonian formulation for gauged non-anomalous chiral theories on a spatial lattice. The formulation has the desirable properties that it provides exact chiral symmetry in the mass + 0 limit, with a correct fermion spectrum and correct weak coupling perturbation theory for QED. It can be generalized to non-Abelian theories. The disadvantage of the formalism is that it is complica...

The Monte Carlo simulation of Majorana fermions is discussed on the example of supersymmetric Yang-Mills (SYM) theory.
متن کاملOptimal lattice domain-wall fermions.
I show that the conventional formulations of lattice domain-wall fermion with any finite N(s) (in the fifth dimension) do not preserve the chiral symmetry optimally and propose a new action which preserves the chiral symmetry optimally for any finite N(s).
متن کاملChiral Fermions on the Lattice
In the last century the non-perturbative regularization of chiral fermions was a longstanding problem. We review how this problem was finally overcome by the formulation of a modified but exact form of chiral symmetry on the lattice. This also provides a sound definition of the topological charge of lattice gauge configurations. We illustrate a variety of applications to QCD in the p-, the εand...

The Overlap-Dirac operator provides a lattice regularization of massless vector gauge theories with an exact chiral symmetry. Practical implementations of this operator and recent results in quenched QCD using this Overlap-Dirac operator are reviewed.
