The overlap lattice Dirac operator and dynamical fermions
I show how to avoid a two level nested conjugate gradient procedure in the
context of Hybrid Monte Carlo with the overlap fermionic action. The resulting
procedure is quite similar to Hybrid Monte Carlo with domain wall fermions, but
is more flexible and therefore has some potential worth exploring.Comment: Further expanded version. 12 pages, plain Te
Large N QCD on the lattice -- A review of recent results in the fermionic sector
It is possible to numerically solve QCD in the planar limit using standard
numerical techniques on existing computer clusters. The basic ideas behind the
computational strategy an recent numerical results in the fermionic sector of
large N QCD are reviewed.Comment: 27 pages, 12 figures, Contribution based on two talks presented at
the ECT workshop on Large Nc QCD, 200
Large N gauge theories -- Numerical results
Some physical results in four dimensional large N gauge theories on a
periodic torus are summarized.Comment: 7 pages, 5 figures, Talk presented at CAQCD0
Exact Chiral Symmetry on the Lattice
Developments during the last eight years have refuted the folklore that
chiral symmetries cannot be preserved on the lattice. The mechanism that
permits chiral symmetry to coexist with the lattice is quite general and may
work in Nature as well. The reconciliation between chiral symmetry and the
lattice is likely to revolutionize the field of numerical QCD.Comment: 30 pages, LaTeX, reference adde
