Preprint: Variational description of statistical field theories...

Hello there,
we would like to announce our preprint

Variational description of statistical field theories
using Daubechies' wavelets,
by Christoph Best and Andreas Schaefer (Uni Frankfurt, Germany)

Abstract:
We investigate the description of statistical field theories using
Daubechies' orthonormal compact wavelets on a lattice. A simple
variational approach is used to extend mean field theory and make
predictions for the fluctuation strengths of wavelet coefficients and
thus for the correlation function. The results are compared to Monte
Carlo simulations. We find that wavelets provide a reasonable
description of critical phenomena with only a small number of
variational parameters. This lets us hope for an implementation of the
renormalization group in wavelet space.

It is available in LaTeX as
