Logarithmic Corrections to a Simple Power Law at d = 4 in 1/n Expansion
Yutaka Okabe · Progress of Theoretical Physics · 1978
The 1/n expansion is applied to the study of the logarithmic deviation from the meanfield power law in four dimensions. The results are shown to be consistent with those obtained by parquet approximation and renormalization-group techniques up to order 1/n.
