Lattice chiral symmetry with hopping interactions

  • 1. RIKEN BNL Research Center, Brookhaven National Laboratory, Upton, New York 11973 (United States)

Description

We formulate Dirac fermions on a (1+1)-dimensional lattice based on a Hamiltonian formalism. The species doubling problem of the lattice fermion is resolved by introducing hopping interactions that mix left- and right-handed fermions around the momentum boundary. Approximate chiral symmetry is realized on the lattice. The deviation of the fermion propagator from the continuum one is small
