  We study the Jellium model of Wigner at finite, non-zero, temperature through
a computer simulation using the canonical path integral worm algorithm where we
successfully implemented the fixed-nodes free particles restriction necessary
to circumvent the fermion sign problem. Our results show good agreement with
the recent simulation data of Brown et al. and of other similar computer
experiments on the Jellium model at high density and low temperature. Our
algorithm can be used to treat any quantum fluid model of fermions at finite,
non zero, temperature and has never been used before in literature.
