Query: Temperature dependent correlation length for the S=1/2 Quantum
  Heisenberg Antiferromagnet on the square lattice   We present an analysis of high precision Monte Carlo data for the two
dimensional S=1/2 quantum Heisenberg antiferromagnet up to $\xi = 95.7(3)$
obtained by the continuous time version of the loop algorithm. Our data are in
good agreement with a prediction of the recent theory (Phys. Rev. Lett. vol.
77, 3439 (1996)) in very high temperature regime, but they strongly disagree
with it in the low temperature regime.
