S. García (Brown), G. S. Guralnik (LANL), and J. Lawson (Brown), A New Approach to Numerical Quantum Field Theory, BROWN-HET-908.
The first paper is by S. García, G. Guralnik and J. Lawson, and was recently accepted for publication by Physics Letters B:
Two talks were given at the lattice conference in Dallas. The first was by García on boson problems:
S. García (Brown), A New Approach to Numerical Quantum Field Theory.
Apparently, no one has tired of that title yet.
Lawson presented a talk on fermionic issues:
J. Lawson (Brown), A New Method for Solving Lattice QFT with Dynamical Fermions.
This talk contains a different calculation than the one presented in the
first two documents. John is now at ICTP Trieste, and his email address is
lawson@ictp.trieste.it.
J. Kogut, A Review of the Lattice Gauge Theory Approach to Quantum Chromodynamics, Rev. Mod. Phys., 55:775 (1983).
A less formal introduction was given by S. García in his prelim talk a few years ago:
S. García (Brown), Fermion Doubling.
When I get a chance, I'll scan in the amusing title page from this
talk.
Yet another introduction is given by Susskind:
L. Susskind (Tel Aviv/Yeshiva), Lattice fermions, Phys. Rev. D., 16:3031 (1977). Of key importance is the
demonstration of the equivalence of the Thirring Model and the XY Model,
which implies that the Source Galerkin methods can be swiftly turned
to numerical problems in condensed matter theory.
