A new lattice gauge action without scaling artifacts
John P. Costella
I describe a new way of constructing a gauge action that eliminates scaling artifacts, by writing the continuum formalism in terms of "gauge links" (Schwinger line integrals) and u…

The aliasing problem in lattice field theory
John P. Costella
The intrinsically nonlinear nature of quantum field theory provides a fundamental complication for lattice calculations, when the physical implications of the subtleties of Fourier…

A strange property of lattices with an even number of sites
John Costella
By examining the behaviour of the "SLAC" lattice derivative operators, it is found that lattices with an even number of sites have a somewhat strange self-consistency requirement f…
