rst-order approximation gives an upper bound on

for all λ.
The real behavior of λ

differs dramatically from both rst-order and second-order predictions
once λ approaches the critical region (λ > 0.85λ

) (see Figure 2.4). Evidently, this fact is due to the
emergence of a long-range order, which is not reected in both approximate t ...
