Fermion-Higgs model with Reduced Staggered Fermions
read the original abstract
We introduce a lattice fermion-Higgs model with one component `reduced staggered' fermions. In order to use the fermion field as efficiently as possible we couple the two {\em staggered} flavors to the O(4) Higgs field leading to a model with only one SU(2) doublet in the scaling region. The number of fermions is doubled in a numerical investigation of the model with the hybrid Monte Carlo algorithm. We present results for the phase diagram, particle masses and renormalized couplings on lattices ranging in size from $6^3 24$ to $16^3 24$.

Bosonization versus the Nielsen-Ninomiya theorem
In the 2D modified Villain model, bosonized chiral lattice fermion operators yield a doubler-free but non-local reconstructed Dirac operator, consistent with Nielsen-Ninomiya, while the microscopic theory remains ultr...

Bosonization versus the Nielsen-Ninomiya theorem
The 2D modified Villain model's Weyl operators reproduce free Dirac correlations in the continuum, and their no-doubler Dirac kernel is non-local, showing exactly how bosonization evades the Nielsen-Ninomiya theorem.
