On the application of field-theory methods in the Ising model II. Calculation of the critical index $\eta$

I. V. Volovich, E. A. Dynin, V. A. Zagrebnov, V. P. Frolov

Abstract: The critical index $\eta$ is calculated on the basis of a functional representation for the Ising model in an approximation similar to the one used in field theory to calculate the infrared asymptotic behavior.
