void Chroma::fuzz_smear ( const multi1d< LatticeColorMatrix > &  ufuzz,
const T &  psi,

int  length,
int  j_decay

apply a fuzz_smear operator to a lattice field

Arguments:

Parameters:
ufuzz fuzzed gauge field ( Read )
psi color vector field ( Read )
psifuzz color vector field ( Modify )
length length of fuzz_smear ( Read )
j_decay direction of time ( Read )
Discription:

The sink fuzzed propagator is calculated by extending the path of the input propagator and is sum of the two contributions as follows: In the positive mu direction ___3 fuzz \ + + + psi (x) = ) U (x-mu) U (x-2mu)... U (x-length mu) psi(x-length mu) / mu mu mu --- mu = 1 In the negative mu direction ___3 fuzz \ psi (x) = ) U (x) U (x+mu) U (x+2mu)... U (x+(length-1)mu) psi(x+length mu) / mu mu mu mu --- mu = 1

fuzz Where U defined in the the above equations is U mu mu length is an input parameter that describes the size of the smearing.

This code assumes that the gauge field has been fuzzed externally.

(Documentation from Peter Boyle's Fortran code).

For smearing at the source the input is a local source.
