摘要：

The low-temperature behavior of the two-dimensional spin-1/2 Heisenberg antiferromagnet is accurately computed through the Monte Carlo method. The energy density behaves as E = -0.6693 + 0.4027T3 and the uniform susceptibility chi = 0.0438 + 0.0322T + 0.0711T2. Comparisons with approximate analytical results are discussed.
