Please teach me this:
In QTF theory of Schroeder,chapter 13.1 saying:
Just at t=0(t=[itex]\frac{T-T_{c}}{T_{c}}[/itex]),the correlation should decay as power law.
Define the exponent [itex]\eta[/itex] by the formula:
G(x)=[itex]\frac{1}{x^{d-2+\eta}}[/itex]
where d is Euclidien space dimension.
I do not understand why at critical point, the correlation function decay as power law.Please give me a to favour to explain this.
Thank you very much in advance.
