Query: Charge and spin correlations of a one dimensional electron gas on the
  continuum   We present a variational Monte Carlo study of a model one dimensional
electron gas on the continuum, with long-range interaction (1/r decay). At low
density the reduced dimensionality brings about pseudonodes of the many-body
wavefunction, yielding non-ergodic behavior of naive Monte Carlo sampling,
which affects the evaluation of pair correlations and the related structure
factors. The problem is however easily solved and we are able to carefully
analyze the structure factors obtained from an optimal trial function, finding
good agreement with the exact predictions for a Luttinger-like hamiltonian with
an interaction similar to the one used in the present study.
